Has anyone else had this problem?

I got morph targets working on my character while on the 4.18 version of the engine, as well as the 4.19 preview. Afterwards, I took about a month break and just recently came back today to work on the game a bit more. For some reason, even though I had literally not touched my game’s code or even opened Unreal Engine at all during my month break, the morph targets are not working anymore. I have no idea what happened; whether it is an engine problem or an error on my part.

Just want some insight because if it’s an engine problem I won’t waste time trying to fix it, however, if it is because of something I had done, I’ll try and fix it.

Thanks for any clarifications/answers.
