Can't Re-mount M2C sometimes.

### Testmerges

### Description of the bug

https://youtu.be/V1SE1vLWhU8

I can re-mount my M2C in the FOB, but once I leave the FOB I cannot. Might be related to #6363 somehow. There is also a secondary bug I cannot reproduce where you simply never mount your M2C upon deployment. That combined with this bug means some people cannot ever mount their M2C, because you cannot re-mount it and you cannot mount it while deploying it.

### What's the difference with what should have happened?

Should be able to re-mount my M2C anywhere, unless for some reason this behavior is intended.

### How do we reproduce this bug?

1. Deploy your M2C
2. Get off it
3. Can't get back on it unless you're in the FOB???
