Incredibly pedantic here but I used to answer every verb, EVERY VERB with the dictionary form. I guess i just liked to practice remembering the end of verbs this way. Today when I logged on I’ve had COUNTLESS answers marked wrong by typing the full dictionary verb instead of the only relevant “stem” (if you could call it that?). This didn’t use to cause a fail, but now, it is causing fails, and constantly so.
Of course since I guessed right I undid them and wrote it the way they wanted, but I wonder if anything changed platform-wise. I’ve had this habit for so long it’s pretty annoying to fix back. I guess this is because some words, probably the ずる/じる pairs were annoying to add variations for?
