Frozen monsters, plus chest glitch

Frozen Hyrri's minion and flame dog top center of the screenshot below. Also of note, the trunk and chest; both had been opened, but were showing a similar frozen state. I had this happen a few times yesterday also, during a lag storm...

While the lag may have been a factor, I don't think the lag is from GGG's servers in my case; I've been having connectivity problems across all usage.
