Oh, sorry. That's an error from not using the NTT beta. Also, make sure you're using the latest version of gel - I thought I fixed it, and the offending line is on a different line for me. Basically, are you on version 1.5 for GEL?
GEL 1.5 hotfix 1? (sorry for being annoying with this, I forgot that I simply named it a hotfix and not the next version) Also, the latest version on the itch is not the latest version - there's a stable beta in the NT discord
