Caching a sim with particle mapping overrides and UVs frozen at a non-zero frame

[tyFlow]

Are you birthing particles over time or otherwise doing anything that would change the topology of the tyCache? The reason the tyUVWFreeze is failing for the first 100 frames of your tyCache seems to me (at first glance) due to topology on the cache changing before frame 100, thus invalidating the UVW freeze data...

If not, then maybe I'm not understanding the problem...
