Crash after cancelling task and starting new one with circle shape

I wanted to generate a circle instead of a square. So I cancelled my previous task and used a circle instead. I got this exception.

This is not a bug. The most likely cause of this is replacing/deleting the mod file while the server is running, from my experience, although it could be due to another issue. Either way, it's something outside of the mod.

Thanks for clarifying! I can ensure that it did not happen due to file movement on my side while the server was running. It sounds like it's similar to #313.

No worries. Yes it is the same issue, but the class it occurs with will be completely random. This can happen with basically any class in any mod or plugin given the circumstances.

Even if you aren't sure how you caused it, most likely you shouldn't run into this again with normal usage.
