I'm glad the issue was resolved.

@joris327 It seems you are completely correct, I just checked it again and the issue is gone, very strange.
(The issue was that I had the complete vanilla tree and disabling this mod seemed to fix the issue)
maybe I was a bit hasty commenting about the issue, I was switching mod presets at the time or one of my other 70 mods was the cause

@Max Power Can you tell me exactly what's wrong? I appears to work just fine for me.

Hey Mr. Mod Author, it seems that Ultimate Tech Tree has updated, as such this mod breaks the tech tree, I greatly anticipate an update for this mod, don't feel compelled to update just because of me though

Yeah I am running both mods, didn't know the refit mod was incompatible with ultimate tech tree mod, woops!

@Max Power Or are you running my conversion/refit costs rebalaned mod also? Running that mod would result in that happening as it is not compatible with ultimate tech tree.

@Max Power For me they're there. Wich ins't surprising since the mod does not modify the tech tree or navy modules. Any chance anither mod is interfering? have you tried running it with my mod disabled?

It seems advanced snorkles don't exist; Vanilla snorkles do though
