here let me parse the bs

after a huge (50) shpeel of warnings i get

NOTE: Only first 50 warnings displayed.

then

Failure - 2 error(s), 320 warning(s)

only error i can see is

LogProperty:Error: UStructProperty::Serialize Loading: Property 'StructProperty /blahblah.Struct_Tier_Saver'. Unknown structure.

which is used in my savegame functionality… dont understand this at all.

every warning i see seems to be talking bout editor materials or stock assets

except for

LogLinker:Warning: CreateExport: Failed to load Parent for Function /Game/Tier/Tier_Actor_1.Tier_Actor_1_C:UserConstructionScript; removing parent information, but keeping function

which i dont understand at all. my tier actor simply holds a custom structure array which is empty. each child actor (TierActor1, 2, 3…etc) are data only blueprints that only need to have their custom structure array populated by me prior to launching the game.

then theres the lightly parsed…

Your structure is corrupt, or has corrupted at some point. It’d be worth re-saving and compiling everything related.

Worst case scenario you’ll have to remake it with a different name.
