Exception when refreshing the Blueprints tab

[danrayson]

I'm running EVEIPH on linux using wine and wine-mono (installed using winetricks), idk if that's going to cause this error though...

I select a BP from the drop down:

And then I get this error:

An Unhandled Exception has occured and EVE Isk per Hour will now close.
This error occured in EVE IPH Version: 5.0.9083.38011

The version I was using was:

I've looked this up, and apparently it CAN be caused by different runtimes, so that'd explain it. In the code it's using a string that's passed to FormatPercent. This might work using dotnet, but when using mono it's failing.

It's probably caused (with my very limited understanding) by passing a string into the format method here:

I hope this is an easy fix to pass in an actual number, maybe pre-cast it to a float/decimal before passing to FormatPercent? Double.TryParse perhaps?
