[Can't fix] A_SetTics disables model interpolation

[TDRR]

Mostly what it says on the tin. Using A_SetTics to set the duration of a frame, disables model interpolation completely until the frame is over.

I've also posted this over on GitHub, but put here at someone else's suggestion (I guess this is checked more often?): https://github.com/coelckers/gzdoom/issues/1568

Sorry, but this cannot work. The model interpolation code operates on the static tics from the actor as it needs to do this outside the active state and won't have knowledge of the custom value you set.
