Facing many NullRefs

[univexnet]

Greetings,

facing many nullrefs and failed trades recently on Pumpfun, any chance theres something new in the contract that is breaking majority of purchases / sales? Would gladly provide logs, but only thing I get is null from pumpFun.Buy(..., ...), also on sell it fails to receive funds and reports that its not allowed and account being null, any clue? Does not happen for every coin, tho.

Thanks & have a nice day,
uni

To add, most issues arise in Sell function, that basically returns NullReferenceException in 90% of times, so buying is fine, but Selling is basically impossible, unless I am missing something.
