Long time player / viewer of these forums but shamefully never posted...until now! I'm having problems while running OTTD 1.0.0-beta2 and was wondering if anyone cloud help.
While randomly playing the following error message appears, pauses the game and crashes with another Error message appearing after it informing me that it could not save the game further as it was recovered from a previous crashed game (which it wasn't).
I am currently adding for example a bus line and then saving...adding a ferry route then saving...all in-case it crashes - which happens randomly... Im guessing here but it looks like the game is planting a tree somewhere and doesnt like the tile it landed on...could be its ear-marked for a local duck pond and the locals dont like it..?

I must say however in the years ive been using OTTD and the various excellent add-ons this is the first Error ive come across!!
Hope someone can help - and apologies if its been posted before...i had a quick look in the search but couldn't find anything specific...
grf list can be supplied if required.
Regards and keep up the god work guys
