Zephyrs are good spammage weapons.
They are. I just discovered that they are now limited. You can only build 25.
Speaking of build limits, there's an odd bug in the game where you have to cue another unit in order to build all the build limit units you can.
In other words, if you cue centurions directly, you can only cue 9. If you cue, say, an adv. robot tank first, you can cue 10. What's up with this?
EDIT: Even odder, after all the cued units are produced, you can produce one only after the cued units are finished. This is only if you cue them directly.
I've had that problem since the first Robot Storm mod I played back in 1.9.5 I think. I thought it was normal and meant to help stem the flow of spammage, or some way the game stops the build limit. I noticed if I tried to cue 10 Decimator, Devastator, or Siege Walkers, it only goes up to 9. Afterwards, I can pop another one out when the cue for 9 is done.
