The preview of version 5.4 was excellent, and after much testing, I switched my project over to this version and all was well. When the official version 5.4 came out, I didn’t worry and upgraded. This version is the most buggy I’ve seen in the 10 years I’ve been working on the engine. Between blueprints that get corrupted on restart, widgets and meshes that disappear when you get close to them … I’m looking for the 5.4 preview if anyone knows where to download it, I’m not even sure I can go back :/.
