Thats really weird. I used no custom resupply modelsHi, Exactol.
a9 is unplayable for some people, because you have packed in a custom resupply locker model that is flooding console with an error message:
Error Vertex File for 'props_gameplay\resupply_locker.mdl' checksum 12704224 should be 799888055
I doubt a9 will be played again, so you should work on your next version. Please avoid packing in any unnecessary models at this stage.
