Jolly Geo timing is off

I have three Jollys (Jollies?) and last night I sent them off to find Gold deposits. The time for a Jolly is 2 hours. My News tab showed them departing at 19:44. And when I checked at 21:44 - two hours later - it said they still had 50 minutes left. I haven't duplicated the problem since I haven't sent them to find more Gold but I find that to be a bit frustrating.

Edit to add another Jolly issue:

Can someone tell me what this (cut and paste from my News tab) means ?

[12:19] System: A Marble deposit has become depleted.
[12:19] System: Your geologist starts searching for a new deposit...
[12:29] System: [undefined text]


The new deposit search was for the Marble that just got depleted. When I got the "undefined text" pop up it said "Geologist finished negative [undefined text]".

So I'm guessing these forums are just to vent? In six weeks I get no reply on my message.

I have seen the [undefined text] message as well. Seems to have started with the start of the science system. The times I have noticed it was with a geologist that can find more than 1 type of deposit. Usually happens 1/2 way through their search.

One would think BB would respond to questions from players. Seems to be no answers to many questions lately....
