Apply compression doesn´t work 4.14.x

Hi, No I´m not on custom engine, i´m using the official releases of the engine…
Yes this will occur everytime I try here on 4.14…I redid a lot of stuff in 4.13 which does not present me that problem, and I migrated everything to 4.15 when it became available, and now everything works well, I will stay on 4.15 I have no need to use 4.14 again…Just for your knowledge, I found one thing which doesn´t work in 4.15, or at least it does not behave like it did before, and is the “Set Child Actor Class” Node, it just make the child actor disappear, but I already found a solution for this…(about the compression problem, probably when I first opened my old project with 4.14 I converted it in place and maybe something corrupted, but it worked before, now I´m using safer ways to do things xD, and my project goes really good!!)Thanks for your efforts!!
