What were you doing when the issue happened?

When the game is loading, there are lots of errors in the client logs about blue power

Forge and Minecraft version

Version de Minecraft : 1.15.2
forge-31.1.63

Bluepower version and build number

bluepower-1.15.2-0.4.188-alpha-universal.jar

Sorry none of these errors are blue power, mostly seem to be evelon_deco (Planet Evelon)

Yeah I saw that, is just because I'm triggering a reload to pull in the dynamic alloy smelter recipes, I'll change the way they are generated so it stops appearing in the stack-trace.

I thought first like you so I have contacted evelon mod author but he told me that because of this kind of error, it can be blue power parsing method :
