AutoCalc flag is not used to calculate spells cost
I was testing a project in Morrowind.exe(with no MCP, MGE, MWSE), and I found that Morrowind calculates spell cost at loadtime, while openmw uses the baked spell cost from the plugin.
Load the test plugin after the adjustment plugin and the result from my spell in
Morrowind: 450(expected)
OpenMW: 60(not using the changed base cost)
You can acquire the spell from Arille or use
player->addspell "atestspell"
