Hello, dsmith!
Thanks for response.
All from 1-4 steps i’ve done already and double checked that this options are correctly switch on. Only overriding of game mode for level was not implemented but i have my game mode blueprint as default game mode in projects setttings. Anyway i’ve checked overriding it but had no success.
As for migrating problems - this is not my case: I’ve started from my project in 4.10 from very beginning.
Looks like i have to redo all in new project and pay attention on what step event s will break. Will write here when i’ll find the cause.
