5 sec spike at foliage

Hi, always if in foliage mode, i select, deselect, remove etc etc a foliage, i get a 5 sec spike, every single time. Why

Log says This after i touch:

LogAutomationController: Ignoring very large delta of 5.32 seconds in calls to FAutomationControllerManager::Tick() and not penalizing unresponsive tests

Every single time man…please help a brother out

please help

Hi, i found out what it is, every time im touching a foliage, ue loads 2gb of stuff into my memory and immediately deleting it. What am i supposed to do to not, to keep it in memory?
