Pleiospilos nelli and P. Royal Flush question

So strang you have problems with these. I find them easy water once a week in spring until I can see the next set of leaves then stop until the outside leaves have withered away then back to watering once a week until autumn/winter sets in and dry out through the winter.

No. I buy nothing that comes from a commercial grower. They are well cultivated plants.
Luckily I haven't killed my four year old seedlings. It only happens with mature plants.

My soil is a mixture of half clayish loam and half rocks. Nothing else. It dries out quite fast, so it cannot be root due to moist (well, not in all occasions).

Watering in very hot conditions could be a problem but not usually in Europe. Well not northern Europe anyway. Maybe if you kept it in a very stuffy greenhouse. In my well ventilated greenhouse they thrive in the summer sun, although I don't force water on them in a heatwave.

Nope. I keep four windows open (I put bricks below the glass to keep it a 10-15 centimeters height gap for ventilation) on opposite sites from March to late November, 24 hours of every day.
