[SBARDEF] the condition check if patch empty/not empty behavior does not seem to be consistent with woof!s behavior

[GameMasterPDX]

in woof, the patch checked must exist or else the game errors, and it specifically checks if the patch itself has no non transparent pixels from what i have gleaned from my testing. in helion, it simply checks whether the patch exists, regardless of if its empty or not, and does not error if the patch doesnt exist, i feel like the woof behavior makes more sense according to the specs definition of the condition
