Cube tracking logic failure on reconstituting cube in specific scenario

[chunkybanana]

To reproduce: Load the attached save, and wait ten seconds. When the cube reconstitution recipe finishes, the cube disappears and a "optimised cube control routine failed" warning appears in chat.

Additional mods used (aside from ultracube+dependencies): Better Victory Screen and VehicleSnap, neither of which should have any effect

thanks for the report, I do see the same issue.

It's pretty weird, it seems like the cube-tracking logic breaks the moment the cube is picked up by the long inserter. It doesn't appear to be an edge-case timing issue, since the issue goes away if I remove and rebuild the inserter beforehand, but it also doesn't seem to be an issue where the inserter is missing from ultracube's cache, because the issue isn't fixed by running /cube_refresh in console. I've never seen a problem like this before, so not sure what is going on yet.

please note: your save is fine, this is only a momentary lapse, the cube isn't actually gone and the mod finds it again a second later (it goes over to the boiler).
