I start opening the entity program call 1.39 upgrade then i add more weapons so i can swap the weapons to any kind of Collections i want to swap. While i done swaping the weapons i use the SBSP tag and open the BSP viewer. Then i click Edit on the left and click Collections twice to have a check on the box. I move my camera screen to look for the collections i have swaped before but after that, my computer turn blue and there some ten or more setence on my screen while turning to blue. It telling me what happen to my computer or w/e it was talking about. It mean my computer has been crashed. Then i start up my computer b.c my computer has been crashed. Then I figured a way out how not to crash my computer again and i open the entity program call UE v1.6 to make sure it didn't crashed but it already again the same thing. Then i start the bsp view, I avoid looking at the ojects, rocks, bulidings, everything. I was only looking at the wall which didn't lag. I check the collections just like i did before then it didn't crash. I wonder why it crashed when i look everything by checking the collections just like i done it before. Any reason why?
