Happen when monk converse units

last game play using Rus against England,when my monk converse ENG’s man at arm , at the same time,he manully delet those units about to conversed , those units turned neutral instead of dead or conversed to mine.
That game happened between 屯长 and el_Guapo

Hey @CHNTuner! Did your monk die around the time it was converting units?

No,just happen when he delete the units at the moment the converse happen
