@squirrel I have an old hosted server running 1.7.10 with some modpacks. It ran great for over a year, but it's been idle since mid 2016. I fired it up last week and the client is crashing out on entering the world. To thebest of my knowledge neither the client nor the server has been updated in any way.

@squirrel After a bunch of experimentation the server appears to be running correctly, but my client dies with index out of bound errors trying to render items and blocks from certain mods. I cracked open the java and it seems like there is an icon array that isnot the correct lngth or there are missing resource files or something?

@squirrel I'm mostly looking for direction in trying to figure out what changed. Grabbing archived copies of the mods didn't help.I can hack the java, but have no experience in the codebase (mostly a C# dev so I can fake java)
