Trying to jettison spaceMINES (second weapon) causes segfault

[Former user]

I attached the buggy save file.

Steps to reproduce:

1. Wait until you're in the sphere.
2. ESC → Inventory.
3. Select spaceMINES.
4. Jettison.
5. Segmentation fault.

Notes

It does not happen if either of these apply:

• You try to jettison the mines on the tunnel.
• You change your weapon to the mines and then drop them.

No other weapon causes this error when trying to jettison them (i.e. spreadGUN).

This is me, I forgot to login before posting the issue.

Edit: Some more information, I think I pick it up right after jettisoning it. Maybe jettison sets some pointer to nullptr but on pick-up, it's used, and crashes?

null dropped weapon before cycling back, resolves #378
