Nothing "happened"
Romania has been a shithole since before the turn of the century. It was a shithole under the Byzantines, it was a shithole under the Ottomans, it became an angry shithole during the Balkan Wars, then it became an occupied shithole during WW1.
After WW1 it enjoyed a brief incline towards the rim of the shithole, before the Axis dragged it right back down into the shit.
Then, it became a Soviet shithole until the 90s, where it graduated to a post-soviet shithole.
Shit is their ontology. There's been no fall from grace nor toppling incident, just a series of often self-inflicted misfortunes that have provided just pretense to avoid materially improving their condition for half a millennium.
