lotta [WRN] Encountered unhandled code SETUPVAL, skipping beforehand im using --encoding=1 it also errors without that but with unhandled operation code (164) bytecode client.txt

[ChloeDoesThings]

When I tried decompiling the script myself, (using Client encoding), it seems there is a problem with the JUMPXEQKB instruction when decompiling. Disassembling itself seems to be fine but it is coming from the lifter. I'll attempt to maybe fix this by creating a pull request.

The issue may be fixed since a pull request of mine got merged. Try building the unluau v1 source and see if it fixed it.
