Geometry Script - functions only work when called from construction script

Does anybody know why the geometry script plugin only works in the construction script? Even a delay of 0 will stop it from executing.

Calling a function with geometry scripting at any time other than constructor doesnt work either. Im kinda lost now because of performance reasons i want to construct the tiles, with a seperate function and a delay so they dont load all at once. Does anyone know how to fix that or maybe a workaround?

PS: the custom event “Draw Rectangle with delay” gets called in the construction script. When i try to call it manually nothing happens. It only works when its directly called from the construction script with no delay
