Description
Caravan Cannon replaces plasma accelerator

Game Version
Stellaris - v2.2.1 (bbf4)

What version do you use?

What expansions do you have installed?
all

Do you have mods enabled?
none

Please explain your issue is in as much detail as possible.
In the plasma accelerator tech (2nd plasma weapon tech) caravan cannons override the normal plasma accelerator weapons. The small weapon slot is also hilariously overpowered...

EDIT: it seems to be just a display bug. When built the ships only have the regular plasma accelarator weapons installed.

Steps to reproduce the issue.
load the savegame and check the plasma accelerator tech or the ship designer.

They made a copy/paste error in the Megacorp weapon file. The used the same component_set as tier 2 plasma (creatively called PLASMA_2). It overrides the original.
I fixed it on my copy by changing this file, so it should be a simple fix.
