This is an incredibly annoying and frustrating issue with your garbage slicer program, that's preventing me from preparing files for printing, therefore preventing me from running my 3d printing business. 

The title says it all. When I select a model I've supported on the print bed in Chitubox 1.8.1, and tweak the raft size to accomodate the supports, When I go back out into the main edit mode, all the other rafts will all change to that new size as well, instead of staying as they were. I've tried carefully maneuvering the cursor so as not to activate other models when switching to support view, but that hasn't helped. I tried closing and reopening the program, and again, nothing helped. At this rate, I'm going to have to redo the entire project file from scratch, and even then, it will probably do this again. 

And don't tell me to use the new 1.9. whatever version, its even worse and more buggy than this one. You Chinese developers have absolutely zero quality control for your products.
