My friend who dos'nt have a acount on Github has been having problems on our server with a group of friends. He has been turned smaller and smaller now hes aproxamantly 1/16th size of a normal player instead of the 1/4. This may be a problem with pekhui but i thought il try sending a problem report here first

/warmest regards Sniffo

We solved it with two commands /scale set pehkui:width 0.25 and /scale set pehkui:height 0.25
