No offence, but no way I would soak a limb in water, that is totaly destructive.

If one needs to bend either wood or glass based composites, the basic thing is heat. Trying to bend glass with heat is probably not going to work until you get to the point where the laminate would sustain damage. Wood on the other hand is often bent with heat. Water is the carier for that heat, in the case of steam bending, the water itself is basicaly a negative. Soaked in water you are getting the thing wet bit not hot. It may well swell and cause damage, or you may get away with it, but a solid rule is that when moisture elevates the wood weakens dramaticaly, so don't draw this thing until you are sure that it is back to 8%.

the twist can also be in the glue lines, which are probably waterproof glue.

The most likely reason the bow is twisted is that it got stored or strung improperly. Those are loads that can be countered simply by twisting the limb carefully in the opposite direction, perhaps repeatedly, let it rest try again.

You can shoot limbs with twists in them. Jay Barrs won the Olympic gold with a twisted riser, a bow that they couldn't sell, the limb therefore tracked like a twisted lim, the risers of the day didn't have lateral adjustments. Within certain limits, twist is oK, as long as it isn't so extreme the string will come off or not seat in the limb tip grooves.
