[next] Custom SPR2Defaults broken (for models only?)

Here is the SOC for the above gif:

Sprite2 SPR2_DRPD
Default = SPR2_TWIN

In 2.2.13 the model without the frame defaults to SRP2_TWIN which defualts to SPR2_ROLL, so the model displays roll frames.

I don't currently have a good resource to test if the sprite fallback is also broken or not.
