I got a 4/3 monkey sub on BTD 5 online. This is one week after the update of monkey sub in BTD 5.

I already have 2 4/2 monkey sub, than, I put another monkey sub and the left side tier 3 upgrade is not working. I upgrade it once more to 4/2, still not working. Now, I upgrade it to the right side before clicking it off, and I now click it off. When I click back in, I got a 4/3 monkey sub.

But, there is no "submerge" button so the left side upgrades are actully useless.
