@Jip starting around 3:30 mark and throgh 3:45, you can watch the expanding engineers to grab hydros. At around 3:40 there is a reclaim action on the hydro from the engineer in front, then the second engineer bumps the first, then the orders just seem to simply disappear even though they are in queue.
I have seen this happen with a commander or unit getting stuck on some reclaim, but what is going on here has happened to me a number of times recently in addition to what @silentNoob showed here: https://forum.faforever.com/topic/6808/degrading-game-responsiveness-over-time-factory-queue-in-particular
It could be a separate issue but still.... it worries me.
Cannot figure out how to take a screen shot while order queue is visible as it "snip it" tool is refusing to work with the shift key held, but here:
