I found a very problematic issue in the engine. I'm running TDM 2.06, 64bit executable, Linux version (openSUSE Tumbleweed x64). The issue is as follows:
Previously, if a bad script or definition or missing asset error occurred, TDM would crash back to the main menu and the error would appear in the console. It seems this is no longer the case and something worse happens instead: Errors will now cause the process to freeze, shortly followed by a permanent black screen.
The reason why this is annoying is because alt-tab switching still doesn't work. To recover the operating system, I need to hit Control + Alt + F1 to go to a different runlevel then use 'top' to find the TDM process followed by a 'kill -9 PID'. Can anyone else confirm this and fix the engine locking up on internal errors?
