Ok guys, iI know howof two methods to fix your problemthis issue. Sorry for bad english, but i try to help, try to UNDESTAND ME
You have 2 options, Method 1 option is with softwarethrough a mod, and 1 optionmethod 2 is through an in game.-game fix:
"IGE" or "IN GAME EDITOR": Just download the mod from Steam Workshop. Enable the mod, then you should see "IGE" on the "upper-right" part of your screen - click on "IGE" and then wait a little bit. You need to find the city with "buggy production" and then edit your production from your city. This resolves the issue most of the time.
In-game workaround: Go to the city which is bugged, click on the city, then click "purchase", then on lower-left part of your screen, you have the "BACK" option and the "PRODUCE" option, you just need to click on "PRODUCE" and check what your city produces.
1.OPTION - "IGE" or "IN GAME EDITOR" can fix your think. How ? Just download from steam, Enable mod, then you can see on "top/right" angleI also get this error because I have lot of your monitor, you can see "IGE"mods, click on IGE and then wait littleseveral mods don't work together, and you can see screenor some mods don't work properly. You needIf you want to find city with "buggy production" and then edittest your productionmods fully, you must play from ancients time to the future. Then you will know if your citymods work without any issues. This is resolve this bug 100%
- OPTION - You have one trick without software. Going to city where is bug, click on city, then click "purchase", then on "left/down" of your screen, you have option "BACK" and option "PRODUCE", you need just click on PRODUCE and check what your city PRODUCE. I know only this 2 for me usefull things, this error i got becouse i have lot of mods, and several mods no work together, or some mod no work properly. If you want to test your mode full, you must play from ancients time, to the future... Then you can know your mod/mods work 100% good. I think i help you guys, this things help me a lot :)
