It's April, time for a new OpenTTD version?
Sort of. We're hard at work on features for OpenTTD 16, but in the meantime we've fixed a few bugs including a multiplayer desync triggered by train crashes.
Fixes include:
Don't desync multiplayer clients when a train crashes
When a helicopter runs out of fuel near the map edge, crash it within the map instead of the void (which crashes the whole game)
Improve appearance of toolbars and main menu images/text with some non-default base sets such as aBase, biggui, and original TTD
If you find any more bugs, please report them here.
