Simulation false positive with 1.8.9 clients and ViaRewind bubble columns #411

Open ZugPilot opened 2 years ago

Describe the bug A clear and concise description of what the bug is.

If you enter bubble columns (translated from ViaRewind) with a 1.8.9 client, it will cause false positives.

To Reproduce Video is preferred. If video is not possible, for bypasses, the hacked client name, version, module, module settings, and the check being bypassed is enough. For false positives, steps to reproduce is fine also.

I'm hoping on https://github.com/retrooper/packetevents/issues/312 as I can't fix these manually without a ton of hackery and spaghetti. Not going to rewrite ViaBackwards.

I think this has been fixed for a long time, this should be closeable
