When I try to install a mod pack at the end of the install I get an error File org.scala-lang:scala-swing_2.11:1.0.1 (C:\Users\nicke\AppData\Roaming\.mineyourmind\libaries\org\scala-lang\scala-swing_2.11\1.0.1\scala-swing_2.11-1.0.1.jar) is corrupt (invalid hash) Expected 'b1cdd92bd47b1e1837139c1c53020e86bb9112ae' Got '7d32320195d4195dde8267b10a08c2f45215dd52' Note -- Expected/Got is different on each attempted load, This is on a fresh install of Windows 10 with Java 8 JDK 8u311 I have tried both deleting just the scala-reflect-2.11.1.jar and the .mineyourmind folder with no change to the issue Modpacks I've tried to install so far are as follows Divine Journey 2 SkyFactory 4 Multiblock Madness Stacia Expert Ocean Block Stone Block Ocean Block and Stone Block are the only 2 modpacks that have successfully loaded so far. update -- after getting down to MC Eternal in the launcher list it loaded, retried all above modpacks seems the issue has resolved itself Since this is no longer an issue I am going to close this post Any questions feel free to message me.
