PIM-SM not working at all

I recently upgraded one of my CCR2004 to 7.1.1 and tried to configure PIM-SM.
Snippet from my configuration:

/routing pimsm instance
add afi=ipv4 disabled=no name=main switch-to-spt=no vrf=main
/routing pimsm interface-template
add disabled=no hello-period=30s instance=main interfaces=sfpplus1 \
    source-addresses=x.x.x.5
add disabled=no hello-period=30s instance=main interfaces=sfpplus2 \
    source-addresses=""
/routing pimsm static-rp
add address=x.x.x.5 disabled=no group=239.254.0.0/16 instance=main

On interface sfpplus1 (with x.x.x.5 address) it is connected to another PIM running on Cisco hardware which has address x.x.x.6 .
As soon as interface is going up neighbor relation is formed and is sustained without any issues.
Then I try to join multicast group 239.254.0.0 from one of Cisco peer downstream interfaces. It appears in UIB G submenu in winbox, but without any RP (despite static-rp entry).
After that Mikrotik drops neighbor relation Cisco peer. Obviously I want to get that multicast stream from another PIM peer, but this issue has to be resolved first.

If there are any errors in my configuration please point them out. Has anyone got it working on ROSv7?

Confirm, in ver 7.1 and 7.1.1 not working.on smips

I also confirmed by switching back to 6.49.2 that neighbour association are maintained correctly in previous versions in the exact same setup.

still not working in 7.1.3

is it solved in 7.2.1?

Not working still. FBI has been notified.
