gratz, actually it are 8x tiles

Im not always happy with such tiles at my homeworld since they can sort of imbalance the game. Last 2 times I wanted to try out thalan all factory's, both time i had an 8x production tile. With the precursor module on it you can produce a simple no engine colony ship each turn, and still have some of your production slider over to generate 1 research point, so creativity can proc.

Strange. I think I've had TA games that had multiple Precursor Mines and Precursor Libraries on the same map.

Edit: Ok, I gone through at least a dozen old saves thus far and I haven't found a map that 2 precursor mines or libraries yet. However, I've saw maps that had 0 precursor tiles, but those were smaller maps (like Tiny sized). Does the map size play a role in how many Precursor tiles there are on a map? I'll try a very big maps for my next few games.

Edit 2: I managed to find a save file that had a very large map. However, I wasn't able to find 2 precursor mines or 2 precursor libraries.
