I've read in a walkthrough, there are supposed to be only 3 on the opposite beach (I was talking about) my game somehow glitched and doubled them, together with their goblin companions. Behold the six Beholders! XD The path down from the Great Knight shrine was normal, there were 2 or 3 Beholders on the road like supposed, but the beach gave me twice the amount of them.
Also Raze's HQ was weird, my previous character had no problems at all, aside from being stuck after the boss battle, had to reload and defeat him again, the current one is kinda weaker (about level 20 or so) and eh died, because the walking armor guys were spawning with the speed of light, there was a huge swarm of them on each side of those spawn machines near the (now closed) entrance to that room, that my game got a terrible lag (even with the 4 GB patch, that solved most issues, the game works smoothly most the time, but once there were multiple red dots on the minimap and not just few, but a real swarm, like at least TWENTY on each side, lag, lag, lag and lag again). Unfortunately I had no save close to that, had to reload an autosave (made at the start of the fortress) and leave the cursed place, time to grind some levels. Didn't ever dream of experiencing something like this.
