Weird Crash Log? Casc bug?

[Strikest]

Found these weird lines in my crash log today,along with the usual failed to access vfs manifest spam:

12/23 04:04:46.026  Accessed Deprecated MPQ for file: Objects\InventoryItems\PotofGold\GOLDCoin.blp   Please import the file into your map to ensure it is available in the future.
12/23 04:04:46.117  Accessed Deprecated MPQ for file: Textures\E_Smoke_Anim256.blp   Please import the file into your map to ensure it is available in the future.
12/23 04:04:46.249  Accessed Deprecated MPQ for file: Units\Undead\UndeadAirBarge\UndeadAirBarge.blp   Please import the file into your map to ensure it is available in the future.

What does this mean? It's not available in the new casc files? Is that what's causing crashes? If so can I import these textures manually to prevent crashing?

No. It's just a warning; those files still exist. Blizzard is telling you to extract them from the Deprecated.mpq and import into your map, because they might remove them in the future.
