Pending rewards/ partial lost

Hello,

Partial pending rewards just got lost when I got paid on the pay day for the tokens,

Example I had 3,5 bat on my pending rewards… and on the payday i only got like 1,25 and the rest just got lost from pending, i contacted support on twitter and he said that the lost amount should be added with the next payment which didnt happend and only got 1,25 paid (Limitation)
