Sometimes I cannot build shipyards - the option is just not there for the planet concerned (playing as Drengin)
If a colony is already sponsoring a shipyard then it can not build another one.
- Annoying issue with "Sentry". I issue the instruction to set my ships to sentry, but it doesn't work. Instead, I keep having to press "Pass" every single turn for all ships I instructed to be on sentry in order to move on in the game. Frustrating.
A ship set to Sentry will wake when an opponent's ship enters sensor range. Use Guard if you don't want it to wake up.
