Hi, sorry for delay.
All duplicated ids have been so far child actors. Onetime it was blueprint placed in viewport (with alt key duplicating). It had another blueprint as parent. Other duplicated IDs have been blueprints with childactor component that have random blueprint glass set in construct script. These bugged actors were duplicated in viewport. By holding alt key. Attached the log.
