Argh.
When you click on your torso, it has 12 crit. slots, out of those you have used 9. In addition over everything you have in your mech you have spent 14 crit slots for structure upgrade, 13 of those upgrades fit into somewhere else than your chest.
Your leg has 6 critical slots, out of those 4 are used to move the leg, and one you have put ammo in. this leaves you with 14 crit slots ocupied in elswhere of your mech, and still one spot left empty in your leg.
If you go and put another SRM ammo into the leg, and check the torso, it will have only ONE lot available any more, as the 13 upgrades that are already elsewhere in the first paragraph dont fit into the leg slot anymore, leaving you with 12 being elsewhere, and two slots taken up in your chest.
so SLOT 16=SLOT 11 OR 12
filling slot 16 with something, leaves you with only slot 12 available.
filling slot 11 will leave slot 16 still empty, there being one more crit slot available.
filling slots 11 and 12 with something, will leave slot 16 full, as ALL of your crit slots have been used.
aka. out of all your critical slots, you have two dynamic critical slots unused, hence you cannot put another double heatsink in, or anything that needs 3 or more slots.
Edit:
Fit it here and you see how dynamic crit slots work, aka. they need to be SOMEWHERE.
