This is the simplest fix, might be best to go with this for develop-ackbar & something more clever can be worked out for develop

I haven't managed to get Twinrova or Freezards to crash with these fixes. However, I did discover another crash. Slashing the icicles near the Freezards in Ice Cavern causes an interpolation crash as well. This seems to be caused by the ice chunks that spawn when an icicle gets destroyed, which is likely the same issue of over-allocation given that's several chunks per actor.

I can fix that crash locally by using the non-interpolated Gfx_TwoTexScroll function here in EffectSsEnIce_Draw:

Shipwright/soh/src/overlays/effects/ovl_Effect_Ss_En_Ice/z_eff_ss_en_ice.c

Lines 125 to 126 in 68cd041

	Gfx_TwoTexScrollEx(play->state.gfxCtx, 0, 0, gameplayFrames & 0xFF, 0x20, 0x10, 1, 0,
	(gameplayFrames * 2) & 0xFF, 0x40, 0x20, 0, 1, 0, 2));
