[1.1.2a] Vermicast tech is not applied to old compost yard

I’ve encountered a possible bug where I had two compost yard built before I invested my first knowledge point into Vermicast, and a third compost yard was built after that.
In section “produced last year” I keep seeing 144 units of compost for old yards and 173 for the new one.
I’ve noticed that after investing the second knowledge point into Vermicast.
After that I relocated all compost yards. Now the vermicast seems to be being applied correctly, resulting in a total of 202 units of compost produced in all yards last year.
