I was giving one of the events my all, was holding my place in the top 3 with ease, and then overnight halfway into the event my progress froze. Goblins made no progress gathering. Barrel launcher gave no more goblins. Even my reward spinner was still set to 0/5. The support did nothing to help. This right here is why mobile gaming is a waste of time. Edit: Here we are months later and events still randomly freeze during sleep. 8 hours passed-zero progress made. Garbage.
