I was trying the improved load balancing over multiple gateways and found that ros 2.9.44
won't accept nth=

I used
[admin@MNS] ip firewall mangle> add chain=prerouting in-interface=Local connection-state=new nth=1,1,0
invalid value for counter, an integer required

where as this works on 2.9.43
and if I add this through winbox then do a print I get

[admin@MNS] ip firewall mangle> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=prerouting action=accept connection-state=new in-interface=Local nth=11,0

if I try add this with nth=11,0 I still get an error

There has been numerous similar issues throughout times. I guess it's a mishap when they consolidate code (code reuse).
