Both swordsmiths Master and HQ guilds are BUGGED

I just build a swordsmith HQ guild and noticed the description says "gives +1 global effect". But the master guild has the same description and it is the guild supposed to give +1 global effect, so the guild HQ are supposed to give +2 global effect...
So decided to test wich one is wrong and found out EVERYTHING is wrong. Actually both master and HQ swordsmiths guilds have absolutely the same effect as the basic swordsmith guild. The basic swordsmiths guild gives +1 in the place where the guild is build and nothing elsewhere. Both master and HQ swordsmiths guild DO NOT change anything. No matter what the description says they works only as the basic guild and give +1 in the place where the guild is build and no global effect at all.
I recruited armored swordsman, dismounted feudal knights and dismounted english knights with no guilds at all, basic guild, master guild and HQ guild and the stats of the recruited troops shows all the melee troops get +1 ONLY in the place where the guild is build and no global effect at all.

Well Im not surprised, this game is so full of so many other bugs and inaccuracies of the things it says its suppossed to do (not historical accuracies, I dont care about those)

Not sure but from reading the export_descr_building file
Its the heavy cav that get a faction wide bonus

Handel, you're misunderstanding the effect. It's not bugged. Well, to be precise there is a bug, but that's not it. The Swordsmith's Guild has two effects. The local effect is to upgrade the melee weaponry of any unit trained or retrained there. It will work on all melee troops, such as knights, swordsmen or spearmen. The global effect is to add to the experience of new KNIGHT units trained anyplace in your empire. If you have a Swordsmith's Guild HQ, that gives you 2 free XP on knights only. The bug is that sometimes you don't get the xp when you first recruit a unit, instead you get the normal unit and then have to retrain said unit to get the experience. The global effect is not the melee upgrading, that's only in that castle or city.
