I changed some very small details in our code (Added some lines in ColonyList.java and renamed a file in the assets to upper case)

It runs perfectly well in intellij, but when I produce the jar all of our users and our official servers throw an error:

Like always buildGradle with travis

And it created this:

https://www.dropbox.com/sh/9cnqcjl0nan57cy/AAB8tv-J7awi-O-BBejOpgkNa/branch/hotifx/mathhelper-crash?dl=0

And I tried the universal one not the deobf one.

Fixed the problem. Always when tests are failing the jar ends up being deobf.
