The old build was left in a bad state by the previous programmer, which had plenty of broken aspects. For example, for some reason we couldn't export without an error which would cause Nile and Poppi to not show up at all. This on top of a lot of caching errors lead me to decide to switch the project to a new build.
Now, the usability of the unreal 5 build is really yet to be tested, it seems like development on it is a bit slow. I have made some changes however to the development pipeline to potentially speed things up. We should see something interesting hopefully before the summer ends.
Maybe it can port to android as well after this.
