i can't tell from the log.

one of the mods is sending a bad S3FPacketCustomPayload, but the log doesn't say which one.

you're going to have to locate the mod by removing them and returning them. either remove half of your mods and see what happens (fastest method) or remove two and see if it happens again, then next two, then next two...

make a new test world, don't do it in your regular world(s).

when you find a culprit mod, either find a newer version or a replacement.
