Introduction
The "reef bug" is an issue in Chapter 7, where you need to use the ship's cannon to shoot down three cult mages performing a ritual on the Devil's Reef. Problem is that neither the Reef, nor the cultists are visible in the PC version of the game running on Windows newer than XP. If you haven't seen how the scene looks like without the bug, I suggest you to lookup a gameplay video with this part unbroken first.
With the targets invisible, thus not knowing where they are, it's practically impossible to hit them. There is a fan made patcher available, which among other also allows to workaround this scene. However, if you learn the locations of the targets in advance, you can hit them by shooting blindly, using just the horizontal and vertical rulers in the cannon scope. And that's what you want to do - shoot the bastards for real!
I learned the locations by watching gameplay videos and then experimenting a bit. It took me a while until I figured the precise locations, because of low/downscaled resolution of the videos, and because there is no hit confirmation, but in the end, I was able to find the correct coordinates.
How to aim
There are three mages. One in the centre, one on the left side and one on the right side. They are always in the same positions and those positions can be hit from exact ruler coordinates.
You must be zoomed in while aiming. Watch how the needles on the rulers move and get them to the required positions, then shot. If you're sure you fired in the required position, go for next target.
Read the coordinates below as the number of ruler lines on which the needles must point. Count the first ruler line from top/bottom/left/right always as a zero.
See screenshots for confirmation - click them to see original size to be able to read the rulers.
Central target
The central target is:

horizontal ruler: exactly the middle
vertical ruler: line 8 from bottom

screenshot:
Left target
The left target is:
(when aiming left, the ruler needle is moving right)

horizontal ruler: line 4 from right
vertical ruler: line 11 from bottom

screenshot:
Right target
The right target is:
(when aiming right, the ruler needle is moving left)

horizontal ruler: line 9 from left
vertical ruler: line 11 from bottom

Got them?
Once you hit them all, the waves will stop and the game will continue. Congratulations! You did it for real, no matter how hard the Elder Gods tried to stop you :) !

controlling the cannon is so fucking ridiculous, i try moving it slowly only to have it spaz out to the other end and then the guy yells TAKE COVER and i have to wait for the next cycle. they only give you like 5 seconds

How are you supposed to find x and y coordinates

Target: (x,y)

Middle: (0, -12)

Left: (26, -9)

Right: (-21, -9)

Get the markers on these Cartesian Coordinates, zoom in and fire. The lack of control, visibility and the incoming waves made it feel like a real battle!

I was just about to make one of these lolz. Mine was going to be really simple though.
The left mage: x56 - y11
The center mage: x30 - y8
The right mage: x10 - y11

The funnies thing about this too, is that you don't know did you hit any of them until you actually hit them for something to happen! :D
