You may find a crash that happens when starting AIs in single player with 'start_spectator' set to off, which is the default behaviour.
Since I got no way to access my computer to fix this anytime soon, here's a workaround, just set 'start_spectator' to on:
- launch openttd
- open the console
- enter: set start_spectator on
- exit openttd
So, the following times openttd is run, the crash should no longer happen.
Fixes on the 21st Dec version:
- Fix: Vertical scrolling issues with Max Ops column
- Fix: Potential crash when more than MAX_COMPANIES could be requested to be created
- Change: Switched the position of Max Ops and Memory columns
- Change: Updated to master version of 21st December of 2019
