Played a pretty congested game with four players each with six man squads.
The side hustle cards are great and added a ton of fun uncertainty eyeing each other up waiting for a card to be revealed.
Unfortunately I rolled like I usually do and limped off the table with only one treasure and a small side hustle objective.
The side hustle cards, in my opinion, are a must buy and add a ton of fun to your games.
Best thing to do is probably just to buy another pot and transfer the glue over as you run out. You can theoretically use most non nylon brushes but it tends to dissolve the glue that keeps the bristles in place, so maybe rinse right away? I've used blunt syringe tips before with some success just using capillary action.
