Hi!
So it's been the 4th crash since I worked on this project. Last time I use replaymod was 6 months ago and I just started a project recently and that's when the crashes start to happen. Everytime I open any replay and hanging around in it for minutes, it always crashes as soon as I pressed the Save & Exit button. I only have Replaymod in my forge and I also have Optifine in my Minecraft.
Here's the log:
