restarting from a save-game seems to reset the gravity to default. Is this expected behaviour and if so, can all the jumps be completed with default gravity? (I am having trouble doing so...) 

It's most probably unintentional, so just set gravity to 400. A similar thing happens in my map but it's purely visual.

As far as I can see there is a countermeasure against this in the latest Quoth but I had no time to attempt using it. 

might be what you are looking for... 

Seems like all I/Kell needed to do was to put spawnflag 4 to info_command... 

There are many maps (not all) that I can't play from the start map : Murkor, Kell, Shotro, Onetruepurple. I don't know what is happening here, it's the first time I see this problem.

When I walk on the portal of these maps, I'm getting an error in the console. I will try more tests later.

Anyone getting these ? 

What is the error you're getting? 

Did you put the whole pack into a jam9 folder or did you extract the maps into your quoth/maps folder, despite being told before that this would not be a good idea? 

Here's what I'm getting : I launch QS (special edition for AD 1.6) and get into the Jam6 start map. Everything is fine then. I directly run into the medium skill portal, then run straight into Kell's portal. I get this message in the console :

"Host_Error : Illegible server message 110. Previous was svc_serverinfo"

What is this ? 

The jam9 folder is not in the Quoth folder. It's placed inside my Quake directlry, like any other mod. I can play many other maps from the start map, so the issue is apparently related to some maps only, not all of them. 

 

moderators, please add this mirror link to the OP: http://www.khreathor.xyz/quake_maps/releases/func_mapjam9.zip

And don't use the -heapsize command as instructed in the readme. Mine works perfectly. 

Is that enough ? I use that value for some other mods/maps which I don't remember.

I can load Kell's from the console. But curiously I can't from the start map ! So why would the heapsize value have an effect here ?

Kell's map is awesome, by the way. I reminds me the movie Evil Dead in some way.

And a modern engine ? What is the latest QS_spike then ? 

when I try to load Kell's map from the start map. I'm still getting the same error message in the console.

What gives ? 

And yet, I can load them all from the console.

Wathever the value I'm using for heapsize or other parameters, I'm getting the same results.

I can load about half the maps from the start map, the others give me the same error message :

"Host_Error : Illegible server message 110. Previous was svc_serverinfo"

What is happening here ? 

I honestly have no idea why it's doing this. None of us have encountered this issue.
What's the path to your installation of Quake? Does it have a space? 

Try with the stable release of quakespasm:
http://quakespasm.sourceforge.net/download.htm
or markv. 

Yeah - I can reproduce that with Quakespasm-spike r7. Just use regular Quakespasm or markv 

I confirm that the official "stable" QS solves the issue (apparently), so it appears to be related to the version you gave me by email.

I'll contact you about this (by email). I still have a few tests to do, to try to isolate the cause.

Demos

Seriously, what an amazing turnout this was. There were lots of unique takes on the theme, and I can personally say that this could be another milestone for the community. Congrats to everyone who participated. It's been a hell of a ride.

Favorite maps in no particular order:

jam9_skacky
Jam9_G1ftmacher
jam9_kell
jam9_pulsar 

Ironically yesterday as I was awaiting the mapjam 9 release I played through Quoth 2.2 and had the exact same error message when loading e1m2; via console or going through the end portal of e1m1.
What's strange is I can load a savegame of e1m2 on Quakespasm spike if I load e1m2 and create the save with regular Quakespasm first. That was my workaround to playing it. 

Ok so I've played through 4 maps going in alphabetical order so far. They have all been fun and had some great architecture and gameplay ideas. I have a zip with the first 4 demos if the mappers want to see me play. Played on skill 2.

Bloughsburgh - Jam9_mjb - Very gory and twisted map. I have a sensitive stomach. Loved the spinning blades. Found a few secrets and ended the map without the super secret. Very neat ideas.

Breezeep - Jam9_breezeep - Loved the castle in a canyon idea. Great arena battles here with lots of room. Found all 7 secrets and had lots of fun.

DelusionalBear - Jam9_dbear - A neat little map. Had a hard time with ammo at the start until I got the rocket launcher. Some tough ambushes on this one.

Dumptruck_ds - Jam9_dumptruck - Great creepy music and new sound effects here. An interesting layout with some thinking about where I was to go next. I died so my demo is a second run. Couldn't find that last secret.

That's all for now. Have a crazy work schedule this week, and still working on my own map. Will continue with playthrough later. Thanks all!

@Redfield thanks for the demo

Seen two playthroughs of my map, not enough for any kind of statistics, but sort of interesting how first secret hasn't been found. I thought connection would be obvious :) oh, well.. next time maybe
