What exactly are you trying to change? Can you send me a video?

i dm u a video discord

did overlaynonscaled like you said but cant edit text now cuz it bugs out the UI

Eta? Its affecting kits too

now with all the addons its getting worse. Please let me know when you can fix this> I cant edit or close the wipe schedule. i have to reload it. Kits is the same way. 

I have to disconnect from server and rejoin so it can fix. but it only fixes for me. everyone has to reconnect to server too to fix. but later same thing happens
