There are two problems of Advanced Tesla coil and HeroTurrets mod. Probably more appropriate place to post this on the Heroturret page, but the author is not responding, and may be you could take a look:
1) A tier bagde of a heroturrent level is hiding inside the Advanced Tesla coil texture in the world.
2) if you change in the settings of the heroturrent, the Killcount to be not "fizzy" but specific, then in the gui of all logic prototype (for example the requester chest request menu), every tier of Advanced Tesla coil appears twice, while all levels of default towers appear once
