EvoGUI v0.4.205
Short version... This one shouldn't be required, unless you're playing Factorio 0.15.22 exactly (bug will be fixed in .23), but I found #74 and (once Rseding91 showed me what the bug was) figured I could work around the Factorio bug to fix it before the next release.
So here's a change wherein I'm renaming the top-level GUI element, which has the potential for some interesting bugs (like, the old EvoGUI GUI might stay behind, the new one might not get created, or the new one might get created but the old one might attempt to be updated...). I think I've done it right, though.
I'll delay releasing it to the mod portal until I have confirmation from a few people that it's working for them (I've since obtained said confirmation).
Important note
After upgrading to this version of EvoGUI on a multiplayer server, save the world and restart the server to purge the save of any leftovers from the old GUI root. Otherwise, I've noticed, you'll still get desyncs when clients connect, probably until the next autosave or something.
