Game Freeze - Breaches in Instilled Delirium Maps

Recently started Instilling all my waystones at end game and the game would freeze up in the middle of a breach fight while in the Instilled/delirium maps, with alt+f4 or Stopping the game in steam to close the game down, the map would be lost every time.

It has happened on multiple occasions yesterday and the day before, not only to myself either, I taught a few guildies how to instil waystones and it happened to them too.

We only learned how to instil waystones 2 days ago, so we believe its this combination which is freezing the game up randomly. This is our assumption.

Stopped instilling maps and I haven't had a freeze since in over 30-50 maps today.
