Happened to me too. I own both the Lancaster Repeater & the Double Barrel Shotgun; yet I can still purchase them, and when I do the same glitch as shown in this video occurs. I hope Rockstar fixes this soon...
I went ahead and got 100% with this play through then started a new save. Haven’t encountered this bug on the new one yet. Rockstar needs to hurry up with a patch though, we shouldn’t have to start a new game just to fix bugs or encounter new ones
In addition to the mana strike X ability which increases damage output by 200% at expense of 15 MP, I used Marlboro mucilage to get deathtouch 2 which makes it pretty OP
Like I said in my previous comment, when it’s jahrk you lvl the MAG stat then mythril bow you lvl fire, ice, and thunder. I was going for all stats somewhat so for the first two stages, gem of disorder lvls mag by 5 and fire by 10% but I when I remodeled to elders bow I wanted str and vit so I used monster jaws. Honestly it depends on what your preference and play style is
It starts out as jahrk with 10 MP and 52 attack.lvl up MAG stat to 30 which Turns into mythril bow then you have to lvl fire, ice and thunder to 30 to get elders bow
It has 20 MP on its own. So far there aren’t any materials that increase MP on weapons. As you lvl it up and remodel it gives pretty good boost to most stats but I lvled up all somewhat cause I like being well rounded
