Not sure these are bugs or features but i hope other people would verify below
1. even though I have 5 machine guns at base 1, I can transfer 100's to base 2. the counter just keeps incrementing
2. soon after I research an item, it becomes available in the market, I pretty much don't need production labs
3. if you equip a fighter craft with only alien technology, it will not work, must have at least one human rocket or machine gun
(clicking on a UFO pops a box that list option missing the fighter)
4. alien activity drops suddenly, I can go for days without any incident
5. soldiers barely improve per mission. in fact only noticeable change is by rank
6. go to production screen, select production of a new fighter craft (the researched ones with no picture)
down below select production of a stun rod. click the line above (figter) the picture the right is wrong.
go back an forth between screens and then go to production screen. the picture to the right is wrong
