You have to trust that router delivers your packet to an endpoint. Encryption doesn't prevent that. And unless you're delivering extra packets to mask your control packets, it's trivial for the router to make drop decisions on packet flow data.

But dropping packets is not supposed to harm because it can happen anyway for various reasons. And a malicious router dropping packets is guaranteed to get some attention sooner or later.

It depends on the drop it causes. If it only increases the drop rate for certain streams than detection will be harder to notice. And of course the perf counters can't be trusted thus making the detection harder.
