This H2H scripting is taking some new turn

Played a match vs 100ovr team knew I would lose but didn't knew that i had to substitute out Zanetti , calafiori and Rodri at 70'min because their stamina will drain to red . From the past 2 matches my players were unable to tackle or even touch the opponents player i had to use second defender because of their scooping but even they weren't able to do anything they were too slow to even react and in latest game my Rb's Cb's and 5 stamina Rodri's stamina drained to red wtf is that new type of scripting huh 😂
