Issue description:

certain items won't render or appear in JEI, but there is a space where they are, here is a screenshot depicting this:

Steps to reproduce:

1. run mekanism with project red and JEI and some other mods
2. view a recipe that involves a derendered recipe (ex: robit)
3. game crashes

Version (make sure you are on the latest version before reporting):

Forge: 2705
Mekanism: 9.4.10.345
Other relevant version:
-jei: 1.5.1.36
-project red: 4.9.0.84

If a (crash)log is relevant for this issue, link it here: (It's almost always relevant)

crash report here

also to add, this issue was originally reported on JEI here

and here is the project red issue as well, here
this issue is also involved in mob grinding utilities

Narrow it down to the minimum set of mods that causes it. Most likely there is a coremod changing things in an incompatible way.

Going by https://paste.ee/p/vEN1N which for some reason has the extra caused by line, Project red is doing stupid shit; TileEntityRendererDispatcher.instance.renderers.get should be returning the instance we registered.

The 'fun' thing is, I reported the same crash to the Project Red author with solely Mekanism and Project Red and its dependencies. They said it wasn't Project Red's fault and we had to open an issue report here.

Lol ya, I referenced it btw

you need to open a new issue on PRed, as the one you linked here was for a separate fixed issue.

This is getting better and better, I had an issue open for this but the Project Red author closed it for being a duplicate of that other one.

So this is a conflict between Project Red and Mek then? My player is getting this crash when attempting to login to the server. His avatar is wearing a Mek jetpack. I logged into my OP account to try to duplicate the problem and was not able to see the jetpack (along with several other things). It seemed like it might be related to this thread.

yup, same crash
