I don't know if this happened recently or of it's always been this way but the nexus hitbox is way bigger than it looks. Specially in the upper direction on redside, if you try to walk towards fountain there's like a lot of space where you can't walk cause your right click command is taken as attack the nexus.
I just had a game today where I died to a 5% hp pantheon cause he was standing next to his nexus and I legit couldn't stop attacking nexus. We won of course but I thought the nexus hitbox is an issue.
