Apparently it's this line:
ifactioncount 1 { sound BLANK }
This particular sound is defined in defs.con, but not mapped elsewhere (and it was forgotten in the mod code as well). Apparently EDuke32 used to tolerate this, but not any more. Therefore, "Moonbase Accident" has been updated with a fix for this sound-specific crash.
To update:
- Use the
EAC Downloader Script (unzip into your EDuke32 root dir and execute eac_install.bat) OR
- Get the updated
EAC Base Pack and download moonbase.grp from the
EAC repository
Regarding "Infestation in Time", I guess we would need logs for that as well. The ingame crash in MSSP seems to be of a different, rather map-related kind (even though I don't even know where it's supposed to occur).
