Like in the case when the Russians hit something in Ukraine, the Ukrainian authorities do as if nothing important was hit, so also the 'authorities' of LNR & DNR para-states are claiming that 'Ukrainians are randomly shelling civilians'...

Su-57: that's just the usual PRBS blah-blah. The type has no operational fire-control system, nor software for integration of the work of all of its sensors. As such, and if deployed anywhere near the combat zone, it would be more of a threat for its own pilots than for any Ukrainians.
