Description of bug: Mindlink gives a message when its paired cast is successful, but gives no such message when it wears off, seemingly to either party, regardless of the order it was cast.

Reproduction steps:

1. Successfully cast Mindlink on yourself or a target speaking a language you do not know.

2. Successfully cast Mindlink on the other party described above.

3. Chat until you stop understanding each other without warning.

No error message or screenshot, but here is a pastebin of the relevant logs during the time period I observed this: https://pastebin.com/8bseJ45V
