I realize this is an old game, but it's fun to pull out every once in awhile. However, I've found that I never make it very far into the game because I'll end up crashing one or more roller coasters on a particular level.
It doesn't seem to be avoidable. The crashes just happen eventually, even if your maintenance worker is checking it every 10 minutes. Every time this has happened, I can't recover or re-open the coaster after it's fixed. All I can do is delete the entire roller coaster, which can be costly and very annoying.
Is there any way (without using a cheat) to avoid the crash or recover after it?
