I was trying to do the easter egg and my friend didnt have enough ammo in his bow (not sure if this had anything to do with it), but he tried shooting the teleporter and he ran out of ammo so we couldnt do the easter egg anymore and we started shooting random clocks around the map and random blue orbs appeared on the bell tower and I couldnt find anything about it online, so I was wondering what it is, theres a picture of it on my twitter, could someone look at it and tell me what it is? @oatmeal000 (not trying to advertise) but Im very curious
