I recently updated my world from modpack version 2.0.4c to 2.0.5. Worked fine until i visited the moon.

^i got these messages in chat. screenshot taken in overworld immediately afterwards. latest.log attached.
latest.log

in addition to the strange chat messages, create moving parts and contraptions were invisible, and there was a complete lack of shading., as shown below.

Any ideas if this is something you can fix in a patch or if i can fix it myself are much appreciated

Can reproduce on v2.0.5. Error occurs when a Create contraption tries to render, which can be done as simply as placing a Windmill Bearing on the moon.

If there's a newer version of iris and sodium available (and iris flywheel compat), upgrade to that. If there isn't, downgrade them to the compatible versions which should be:

Should be fixed in 2.0.5b
