Hey there @Jonner94! Welcome back to the community! Rollback with blueprint would be a difficult endeavor. If you were to require it, I’d recommend working in C++ and you’d require custom tick and everything you’d do would have to be determinate so nothing with built in physics. A great writeup by Rufus on this thread can get a bit more of an idea from a high level. Depending on your use case, there are also some tutorials that will help you with the general idea.
I know GAS (Gameplay Ability System) implements something similar to rollback but it’s outside of my wheelhouse and I can’t find a proper resource on it.
