[A16] Imprisoned Colonist's [Needs] tab causes lag

[Encode]

Imprisoned my pyromaniac colonist who went on a firestarting spree, and it happens when I clicked on the [Needs] tab of said imprisoned colonist after it was up and walking about, I noticed the entire game starts to jitter/lag so much.

I can't say for sure this is a 'bug' but anything that causes lag for no reason, I feel it should be looked at. Thanks!

I can't reproduce it, maybe it's already fixed. Could you please upload the logfile?

If you're on a large map or something CPU intensive is happening on the map could be causing this.
