In the latest build (896), OnEnterTrigger seems to only work the first time they are entered.
I'm using it for occlusion/enabling/disabling objects in certain areas.
I've tested with my 2017 world both in live and beta, and the issue is only in beta.
The same happens with my 2018-beta version of the world that I'm working on (using SDK2-2020.02.03.22.36)
Additionally, since I use these triggers to disable certain areas... respawning now often causes me to fall through the world.
