Randomly the replay mod started crashing while rendering and im not sure whats causing it. Ive done nothing differently than ive always used the mod and suddenly it just started crashing afte rendering a camera path.

here is the log though if it helps
latest.log
latest.log

Looks like an Optifine bug to me - I had several similar crashes when I was still using it. It doesn't log exceptions and just crashes like the process was shut down.

Neither log contains the crash report.
