Hi. I just got an error

Internal compiler error inside CreateExecutionSchedule (site 2); there is an issue with node/pin manipulation that was performed in this graph, please contact the Blueprints team!
The property associated with Overlapped Component could not be found
ICE SetVariableOnPersistentFrame - No property found. Overlapped Component
[6056.33] Compile of CheckPoint failed. 3 Fatal Issue(s) 0 Warning(s) [in 168 ms] (/Game/Blueprints/CheckPoint.CheckPoint)

Maybe there is a way to fix it?

Doesn’t ring a bell, but usually i have encountered such errors when i imported a project from an older version of the engine or changed something significant that node relies on. Try to recreate that node from scratch.
