Am i the one to think that the translation got quite bad after 72/73 chapters??

You might be confusing the officials with the fan translations. The official chapters for season one are uploaded here, from ch1 till ch74 to read.

Then there are fan translations aswell for ch1 to ch74 + currently ongoing with s2.

Anything after ch74 is currently only available as a fan translation by scan groups who do this for free, as we are awaiting official translations for s2!
