What happened to the nodes in SG and HK? Now im completely unable to use mudfish at all
Could you please explain little bit more? I can’t understand what ‘unable to use’ means. Are you meaning you can’t find the mudfish node list for these nodes?
the usual nodes that are good for using in the game im playing is not usable anymore.
Did you try to check How to check the basic functionality section and test with SG and HK nodes?
If it doesn’t work properly for this test, it means there’s another hidden issue. Please test it first.
upon checking the RTT was the problem. SG and HK is not showing on the RTT choices anymore
Then please unset or clear the configuration at ‘Setup -> Nodes’ to see all available mudfish nodes first. 
That’s the problem all the available RTTs are not good for the game
