Editor asks to check out Transient REINST external actor.

Hi,

did it happen to anybody? Is it normal that editor wants to check out a transient REINST package? I just replaced an actor on a level which is already source controlled. However, I also did some C++ work on components’ construction and I’m a bit worried it might have caused it. I replaced the actor on the level as it didn’t show a static mesh component attached to it in blueprints.

If it’s a normal behaviour in 5.3 when replacing an actor on a level which is already source controlled, please let me know. Any information would be helpful.

P.S.
When I tried to check it out I got a warning:
