i am not sure if this a bug or not or something i was unaware of.
i am using TG 2.5.4.0 deep, 64bit
i have been working on my roadside scene, and i find tg occasionally re-populates objects somewhat randomly, unlike when you alter terrain.
its a issue because i have a about 5 or so grass populations that take a lot more time to calculate with their spacing.
examples-
-on doing a crop render
-changing detail/aa settings
-changing cameras
-enabling disabled surface layers.
also, repopulate every frame is disabled.
