I'm working on an out and back woodie that calls for a LOT of custom support (using bigburger's 30cm). I have completed the first hill and half of the second, but the file size is already at 9,000 and failing to load. The load fails at 'post-activate', the game crashes, and I get the 'RCT3 closed unexpectedly' error. How do you support a wooden coaster without crashing your game?

9,000 what?

Make sure you have all Bigburger's Timber sets installed, and if that doesn't work, move your park file to your desktop and use the .dat.bak file and take off the .bak part. That's just a backup file.
