Hello,
I've encountered a strange behavior with construction bots. It appears that they ignore a placed blueprint and they start working only if something changes.

Steps to reproduce:
1. Place a miner manually (I've tried the second from the top in the right most column)
2. Release all construction bots from the inventory
3. Wait around 5 seconds
4. Bots will pick up the material and finish the rest of the blueprint

You can swap steps 1 and 2. In that case it takes somewhere between 1 to 10 seconds for bots to start working. The delay is the same when I reload the game but varies if I close the application and start it again.

Expected behavior:
Bots will start building as soon as I place the blueprint.

Savegame attached.

Thanks for the report however this is working correctly. You have 2500 tile ghosts waiting to be built and the game only processes 1 ghost per game tick so it takes 41 seconds for the game to check everything once and then start over.
