Gold production problems

Morning Folks

I have been noticing a lack of gold production lately on my island, so I decided to do a little research starting at 12am last night.

My gold production produces roughly 43 coins per hour when buffed. So from 12am until 8am this morning, at 43 coins per hour this should equate to 344 during that 8 hour period.
So I done some basic math to find I had actually only produced 187 coins in that 8 hour period. My buffs had no run out as I timed these to end specifically when my buff buddy gets up for work, nor did I become short on gold ore and gold bars.

Has anyone else noticed anything similar with their gold production? It may be worthwhile doing some checks because my production clearly isn’t producing what it should be.

Can a MOD offer some advice, it is only recently I have been noticing this, but then again I never used to check!
