Bug Details & Steps to Reproduce

When starting up my node I encountered the following problem:

2025-11-19 20:20:02.732 [ERR] LTND: Shutting down due to error in main method rev=b9ea70 err="can't create mission control manager: unable to decode error update (type=*lnwire.FailTemporaryChannelFailure): error parsing extra TLV bytes: unexpected EOF"
2025-11-19 20:20:03.816 [INF] BTWL: Stopped waiting for wallet sync due to error: wallet shutting down
2025-11-19 20:20:03.896 [INF] LTND: Stopping pprof server... rev=b9ea70
2025-11-19 20:20:03.896 [INF] LTND: Shutdown complete

Had to delete the MC data to startup properly.

Probably related to https://github.com/lightningnetwork/lnd/pull/9897/files#diff-f8331ad681be444816d76dee176dc2fd628e4be3a0b84466c1458bdba43507f3L164

now we try to decode the Inbound fees and for some reason some reason the result data is malformed.

In general we should just ignore the failures when starting up, however we should also thing of a possiblity to delete this data if we cannot decode it.
