On the improvements screen where it tells you the number of imrpovements and improvements slots you have, most people it will be saying have negative slots.

Eg, A nation with 3500citizens and 7 improvements is reported as -4 improvement slots available (as in the old system they could only have 3).

Needs an adjustment with the new 500citizens per improvement amount.

Check your numbers again. The 'Improvement Slots Available' should be correct.

Apologies, I didn't explain which screen very well... not the screen when you buy improvements, the screen where you view them.

This happens across the board with all nations.

I understand that, which is why I reported it, it is still a bug.

Ah, I was looking at the wrong screen before. The issue has been corrected.
