so i was at 9 acre/turn exploring before i activated my 10% exploration bonus.

after i activated the bonus, i was still at 9 acre/turn. is this a possible bug? or could this be due to some rounding error (not sure if acre/turn is rounded)? so i can imagine a situation where the actual acre/turn is 8.5 but rounded to 9, then adding 10% would be 9.35, which still rounds to 9.

Yeah, I think it's rounding. I had 40 * 15% round to 45.

It also told me that my apt would drop at a new acre amount. That is: at 40 apt, it would drop at 1924 acres, but at the 10% bonus it said it would drop an acre at 1600ish acres. So I assumed the drop rate is also affected by the bonus.

The strange part, however, is that I did it with the 15% and then it told me my country was too big and my apt would never drop (though that is obviously a lie) at 45 apt. So I'm not sure if you meant for the apt drops to change or if it's just an issue with the advisor coding.

not a bug, just rounding

and what Tertius said is correct (the 1st & 2nd paragraph)

i have been getting the same message as tertius in regard to my apt not dropping.
