NPE on startup if mods/1.10.2 is a file, not a folder
RagingCactus opened this issue ยท 0 comments
Somehow I managed to create an empty file called '1.10.2' in my mods folder when upgrading my DW20 server. CCL crashes on startup. Important part of FML log:

NPE on line 63 here
versionModsDir.listFiles()
returns null because versionModsDir was not a directory in my case.I acknowledge that this was a derp on my part, but I think it wouldn't hurt to not NPE here. I still would have no clue why this happened if the mod wasn't open surce. Maybe change line 62 to
if (versionModsDir.exists() && versionModsDir.isDirectory()) {
I don't want to PR this because I've never worked with MC mod sources at all...
