Mixed answers between channels

[XtoZee]

Good day.
I'm using mikronode mainly for mikrotik router port manipulation.
During initial state I disable needed ports in loop with promises using one persistent connection to Mikrotik and one-per-command channel. I tested "bad port" port situation and noticed that sometimes i get "no such item" error on working, configured ports that usually work OK. And that happened right after real "bad" port.
Normal situation:

[19.06 08:46:08] ER: 0:ether28 port down failed!!! Reason: no such item
[19.06 08:46:08] OK: 0:ether14 port down
[19.06 08:46:08] OK: 0:ether13 port down
[19.06 08:46:08] OK: 0:ether12 port down
[19.06 08:46:08] OK: 0:ether11 port down
[19.06 08:46:08] OK: 0:ether10 port down
[19.06 08:46:08] OK: 0:ether9 port down
[19.06 08:46:08] OK: 0:ether8 port down
[19.06 08:46:08] OK: 0:ether7 port down
[19.06 08:46:08] OK: 0:ether6 port down
[19.06 08:46:08] OK: 0:ether5 port down

Bad answers:

[19.06 08:46:17] ER: 0:ether28 port down failed!!! Reason: no such item
[19.06 08:46:17] ER: 0:ether14 port down failed!!! Reason: no such item
[19.06 08:46:17] ER: 0:ether13 port down failed!!! Reason: no such item

[19.06 08:46:17] OK: 0:ether11 port down

[19.06 08:46:17] OK: 0:ether9 port down
[19.06 08:46:17] OK: 0:ether8 port down
[19.06 08:46:17] OK: 0:ether7 port down
[19.06 08:46:17] OK: 0:ether6 port down
[19.06 08:46:17] OK: 0:ether5 port down

After turning on debugging I saw (if I understand it right) real problem - the answer is received in the same channel and what is more strange - seems that channels are not created right.

There's one incorrect answer right after the real "bad" port operation.
There can be upto 6 answers in the same channel.

Another bad thing is that in last log 2 ports "ether5" are downed on different connections to different routers but work on the same channel.

I may be wrong in my conclusions but please explain me what i'm doing wrong if I do.

Node: v.8.9.1
Mikronode: v.2.3.11
RouterOS: v.6.40.3

Is this still occurring?

Haven't seen this for now. But this surely needed some special conditions (that I don't know) to repeat.
