It seems that there are weapons with with the designation "wide" or "omni" that have an extra degree arc slapped on them. The concerning part is that the [arc] mod is not present and yet the omni beam is still 360 and the dual heavy cannon is still 90.
Omnis/wides that do have the mod still show as 360/90 respectively.
How will this bug be fixed? Ignored and let some lucky people get 5 mod weapons? Fixed and current 5 mods stay 5 mods? Or fixed and wide angle dual heavy cannons and omni beams become 45 and 270 degree weapons respectively?
Strangely enough, this only seems to be the case with the wide arc cannons. Beams seem to incorporate the arc into their mod limit. At least that's what i can observe on the exchange.
On tribble though, when trying to craft those weapons, the arc mod seems to be deliberatly incorporated into the weapon and 3 or 4 random modifiers can occur on a single weapon (both on cannons and beams).
