v0.17.2-beta

c:\MCServers>mrpack-install "c:\MCServers\mrpacks\Prominence II [RPG] 2.8.4.mrpack" Installing "Prominence II [RPG]" from "c:\\MCServers\\mrpacks\\Prominence II [RPG] 2.8.4.mrpack" to "c:\\MCServers\\mc" File path is not safe: c:\MCServers\mc\mods\do-a-barrel-roll-3.3.7+1.20-fabric.jar
