Items freeze, disappear, or the ME system doesn’t recognize them.

The issue with some items freezing in the ME system when viewing their related crafting recipes persists. The only solutions are either pulling out the Storage Cell or reloading the world.

At certain crafting stages, the ME system freezes. Similar to the issue with the BatBox in the video, I also encountered this while crafting circuits (a problem with copper cable). When ordering a BatBox, Tin Cables disappear in the system, causing freezes and disruptions in earlier crafting stages. Additionally, rubber couldn’t be retrieved (a previous issue, but this time without opening the recipe through HEI—removing the Storage Cell helped). After a "reload," 3 Tin Cables appeared, which were created during the first attempt. The earlier stages became accessible, but now the system doesn’t recognize Tin Cables for the BatBox crafting.

All patterns were manually created using crafted items.
