- When upgrading neck, I had to stop my workers, because it telled me "position invalid". If something is near the neck at the end of upgrade it can't upgrade.
Elim, is the upgrade for the nest ("neck") larger than the first one? If so, that would be the problem. It's like upgrading a technician to a battle machine. The battle machine is size 2 while the technician is only size 1, so there needs to be space around it to upgrade. I wouldn't recommend making a building grow in size when upgrading, otherwise if you place it near an object, you will be unable to upgrade at all. If the upgrades absolutely must be larger, then increase the size value of the first stage of the nest. It would leave some empty space, but would help prevent this issue.
- Another point is that upgrade abort all the queue. It can't be queued (maybe it's normal ?!?)
If I understand you correctly, trying to do an upgrade doesn't add it to the queue, but replaces it? That sounds like an engine bug. Which one and what version are you using?
- Other thing : I couldn't upgrade my second neck, until I upgrade my first neck from med to large. After that I wasn't able to upgrade my second neck from med to large, and my third
to med.
Ok, you got me stumped there... My best guess is that the unit requirements are requiring the previous nests?
