This blue print crashes everytime I spawn it… but if place in world it is fine.

Ok I got it figured out… the object that spawns it was scaled really high and when it spawns the object it spawns the object at the same size making it crash. Had to make transform on the spawn to set it to normal and it works fine.

Just in case: don’t forget to accept questions (tick at the left top corner of this answer). I sure you don’t want let this question unresolved :slight_smile:
And 0xc0000005 is memory read/write access violation. Happens when you trying to write/read to/from address, that is not in allowable range (like 0x00000004 or 0xffffffff).
You saying, that scale of your actor is huge. Then, possibly this actor was below kill Z while it was trying to interpolate it’s location.
actor is above kill Z → interpolating… → below kill Z → destroying actor → trying to interpolate actor, that not exists, or whom resources were released.

hello! can you help me diagnose this crash report?

Fatal error!
