Summary0002692: Bot Node Overflow (?)
DescriptionThis issue has been in existence since SkullTag 97D, though probably safe to assume - since forever.

The demonstration PWAD that I have provided shows a crash or hang that occurs when adding just one bot into the map. When the crash or hang occurs, there's no useful information presented to the user -- only course of action is to terminate the PID.

I am unsure if this is even remotely fixable as it seems to be the design of the bots SkullTag uses, ZDoom's Cajun bots ['http://zdoom.org/wiki/Bots [^]' ] do not have any issues with the demonstration map.
Steps To ReproduceUsing the demonstration PWAD:
Go to MAP01 and set the gamemode to 'Deathmatch'. Once the map reloads to MAP01, add a random bot into the game.
Zandronum should hang within the first second.

Should be fixed now. It was caused by the size of the map, but not because the map is too big in general, but because the code made a wrong assumption that lead to an infinite loop.

Using build 3.0-alpha @ 160403-1900 - Commit 96e0e5e40e46, (credit to WaTaKiD), this seems to be fixed for me. I have tested this out on a gameserver environment as well as single player environment, seems to be working just fine now. Thanks for fixing this!
