Polybian Reforms

[d'Arthez]

That is normal. You need to upgrade your Camillian MICs to Polybian ones.

When Marian reforms trigger, you need to build a new MIC. I think, but I could be wrong, that the script will check for the level of MIC you have in each province and grant you an equivalent Marian MIC.

Upgrading from Marian to Imperial is similar to the upgrade to Polybian units.

When upgrading from Camilian to Polybian or Marian to Imperial, you can upgrade a lvl5 of the Camilian / Marian to a lvl5 Polybian / Imperial MIC.
