Hi OC_alexm2206,
do events of level static actors handled by the level blueprint work? I.e. Events handled by the level blueprint, but broadcasted by the actor, for example the ‘On Actor Begin Overlap’ event of a placed Trigger Volume.
One other thing I would recommend is that you try to replicate this issue in a new empty level and or project. I cannot seem to replicate it myself, and if you need to report it as a bug you’d need a replication procedure so the Unreal Staff can help you.
As far I can tell this isn’t really a common issue. I couldn’t find anything in the forums nor Unreal’s Issue tracker.
As far as solutions go, I can only suggest two to you. First would be to try to push the level blueprints functionality into a level static actor. The second one would be to recreate the level from the ground up (new level), although I’m pretty sure you aren’t particularly thrilled about this solution.
The first solution would probably the least amount of work, but won’t mitigate the problem itself, it’d be just a work-around and might cause more problems. The second one would be the one I actually recommend, plus if you can replicate the issue this way you can file a bug report with good chances of being fixed, although this might not be feasible.
