For Mongols, the new “Improved Superior Mobility” from the Ovoo gives “+70%” faster move speed for packed buildings. However, future buildings built after researching this upgrade only have +44% move speed when packed.
Existing Packed Buildings (Buildings that exist when research is completed):
- Move Speed [Base]: 0.75 tiles/sec
- Move Speed [with Superior Mobility]: 1.125 tiles/sec (+50% = 150%)
- Move Speed [with Improved Superior Mobility]: 1.35 tiles/sec (+80% = 180% = 150% * 120%)
Future Packed Buildings (Buildings built after the research is completed):
- Move Speed [Base]: 0.75 tiles/sec
- Move Speed [with Superior Mobility]: 1.125 tiles/sec (+50%)
- Move Speed [with Improved Superior Mobility]: 1.08 tiles/sec (+44% = 20% * 20%) <<< problem!
It seems like somehow the “+20%” that the improved upgrade gives overwrites the original “+50%” base value, so we end up with 120% * 120% = 144% = +44% move speed, instead of 150% * 120% = 180% = +80% move speed.
Also, yes, the upgrade actually gives +80% move speed, but I’m putting that in a separate bug report.
