Screen Freezes since last big patch

Big explosions cause the screen to freeze requiring a logout to resolve. The game keeps playing in 1 to 3 fps but the player and the screen never change.

This happens routinely in blight and occasionally in harvest. Just happened in a delve harbinger but delve and maps run well enough.

I never saw this before the last big patch. It took five years to finally get blight running well in the Kingsmarch expansion, hope you get it put back together again.
