So today I decided I'd spend most of it on playing Foundry missions. Got a lot of nice Dilithium and Fleet marks from the Investigate Officer Reports mission. I always make sure I tip because as an author I know how much time it takes to build each mission. However I ran into this problem!
Apparently you can give out tips only so many times per day. It makes sense to stop it from being a way to transfer dilithium between accounts but wouldn't a better solution be to limit the amount of times you can tip a specific player?
