I was starting to work and i didn't try 5.5 model until today. i wrote first prompt "hello bro", model answered and i did command /clear.
terminal window cleared and i did look at other screen to prepare other stuff to start coding and then i saw terminal with codex flicker and when i looked back 5h limit was on 93% and all i did when i started codex was "hello bro" and /clear.
I am not writing to reset my limits or anything like that, but to fix this bug if you can find out what happened there
