Sometimes the sand in my timer will just randomly stop falling, essentially "breaking" it. I am a bit disappointed that they included such cheap timers in the anniversary edition. If anyone has any suggestions on how to fix it, that would be great, but I'm not keeping my hopes up. Anyone else have this problem?
Sounds like you got a specific faulty timer - the timers I've come across in copies of the game have all been fine aside from the standard problem with every sand-timer I've ever seen where the last half-second or so of sand doesn't always fall (which is easily fixed with a quick tap).
The timer's not a crucial part of the game anyway - you can always resort to gently tapping people on the head with the box lid like the rulebook suggests
More seriously, any way of putting in an optional time limit would work.
