Confused by XG weapon requirements

[karadoc]

I've just researched XG assault, and XG rifle. I can now build the ammo, but I cannot build the weapons themselves. The game hasn't given my any hints as to why I can't build them.

I just checked the wiki to find out what's going on, and I discovered that I need Gauss Defences in order to build the XG weapons. That seems strange to me, because I can't yet build gauss defences; in fact, I can't even research them yet.

Why can I research XG weapons without this prereq. even being mentioned? Have I done something weird?

(By the way, I'm still on 0.98B. So if this has already been changed, then I'm sorry for bringing it up. I didn't see anything about it mentioned in the changelog; other than maybe "Research & manufacture updates & fixes".)

You might need a gauss defence in your hideout to build xg weapons: https://www.ufopaedia.org/index.php/Manufacturing_(Piratez)

Yes. The info was missing from the Pedia.

Fair enough. An update to the 'pedia would solve the issue for me. The only problem was that I didn't know what was required to build the weapons. So if that's now shown in the 'pedia entry for those weapons, then that's the end of the problem.

Thanks.
