[Bug 🐞]: Part repairs do not work and throw errors in the log

[astronut42]

Brief description of your issue (aka the problem)

When attempting to repair a failed part, clicking the 'repair part' button in the part's action window does not appear to have any effect. This occurs regardless of the type of repair (remote or EVA). On each repair attempt, a NullReferenceException error is thrown in the log.

Operating system

Windows 10

KSP version

1.12.5.3190

Version of addon

2.2.0.0

Steps to reproduce the behavior or issue

1. Launch a vessel
2. Wait for a part to fail (this may take multiple reverts)
3. Attempt to repair the part, either remotely or via EVA, by clicking 'repair part' in its PAW
4. Observe absolutely nothing happening

Expected behavior

Some indication that the part repair has either succeeded or failed

Actual behavior

Nothing happens in-game, but errors are thrown in the log
