I think this has gone a bit under the radar, so I'm posting a proper bug report. (hopefully)
The multipliers in PacingDefs.xml targets the same range as normal factories/research labs, making the effect negligible. (Meaning the penalty is literally -2 factories worth of production instead of a global penalty as it should be) I tried modding it to raw production instead, but it faces somewhat the same issue there. (same targets, the approval bonus countering it etc.)
If you guys could make global stats targeting tech and production costs instead, that could be a possible easy fix.
