I found a few bugs and rather than take up the comments section I thought I'd put them here

1. One of the direction indicator cubes on the rotated junctions (I only tested the autocannon one) has inverted faces

2. The rotated junction (again only tested with the autocannon) outputs to the side with a single split down the indicator as opposed to the vanilla one that defaults to the one with two indicators

3. Missing description on ammo belt rotator base
