loading issue (strange bugged towers?)

was messing around with my mod pack, everything was loading fine before had bliss and everything running fine, and now all of a sudden there's a issue with random towers loading in, i have no clue what could have caused it. flying into them fixes it and sets it back to what it actually is suppose to look like but the issue is theres far too many of them to fly to each individual one, anyone know how to fix this? possible mod incompatibility?
