Radio FAIL after ~3 weeks [SOLVED]

@Reza:
I tried to reproduce the errors shown by your log.
Part of the errors could be reproduced.
So if you are leaving range of stable connections, node will try to get an new parent (within range). So broadcasting for new parent is "normal". As long as there is no valid connection node will reject sending messages because "Transport Not Ready". So this is "normal", too.

Leaving range resulted in one or two NACK, then connection died quietly. I never got this amount of NACK you got.

I could not reproduce !TSF:MSG:LEN:0!=8 or something similar. This means the message has been crippled (possibly).

Reviewing logs and testing on my configuration revealed no clue to defective Chips (in regard to NRF24L01). Chips could be fake though, but at least software functions seem to be ok.

Fake NRF modules are reported to have very varying (worse) connection distances, sometimes down to a few (possibly only one) meter(s). Maybe -- may be not.

There are two major differences between our setups. I am currently not working with ACKs, I will test this tomorrow.

Second - I got no actual relays connected (only LEDs). You reported transmission break down simultaneously to pressing switches at higher rate. Are you supplying DC for relays from Arduino or from separate DC-supply? Have you made any arrangement preventing inductive spikes (ferrite rings, self-induction recuperation diode etc) ?
If you simply unhook your relays and try again - you get better results? (since your non-inductive sensors work well).

If this will turnout true - you may give Solid-State-Relais a try.
