I have learnt that it is 100 before.

After the update, I have dwellers forced recall carrying only 81 items.

I have an explorer doing the 84 hours wasteland objective, I am afraid it may have collected more than 80 items before the 84th hour and got the trip terminated.

It is now 66 hours.

Just collected one with only 71 item, with 8 stimpaks left but cannot explore.

Is this a bug?
