* Fixed MD2 interpolation not working under certain circumstances (particularly if an object’s state has a finite duration normally, but the object has made it infinite instead).
Up until 2.1.20, MD2 interpolation changed dynamically depending on how many tics the state was set to; however, in 2.1.20 it now it seems to have a maximum interpolation duration of whatever is defined in the state.
hw_md2.c line 1350 - if (cv_grmd2.value == 1) + if (cv_grmd2.value == 1 && tics <= durs)
I do notice that in Castle Eggman 3, with the MD2 active, if I'm standing on the edge of wall then Eggman ends up getting undrawn completely, as well as like the first 2 balls in the chain, let alone further out. I even have my draw distance turned all the way up, yet it's still like this.
