the curse icon, and the second artifiact stil show the wrong tooltip when hovering over it IF you first moved over the bless ability or on artifiact 1 or 3. if you go straight to curse, or to artifact 2, then the tooltip is correct.
copper and tungsten refining is bugged: if you increase the skill to DECREASE the required materials, then the required value goes UP. and the dispayed value goes to 0, you have to change the level above the icon to a higher level and reduce again to see the real value. zirc value goes correctl down but still displays 0 after you buy an upgrade.
not so urgent, but: mining and smelting stats are still messed up. whenever you open that screen, or when you buy an upgrade for any of them, the DISPLAY numbers for the stats go back to default. like the hit points of the ore goes back to the original 500, even so you might have bought 10 reducement for them already. and it looks like that in some cases that the game is even using these dafaults again, instead of the real values. you can fix this by buying one upgrade for each, and then the values are correct, but this is a lot of work, and really annoying. like right now my damage on copper and zirc both shows 10, even so i have bought 37 upgrades for each, and the hit points bar is not going down. the real value should be much higher. and i can see that the end result is meaning i am loosing zirc and copper (as I am refining). and yes, this happens after rebirth, or while in the game, or while switching screens within the game.
ah, about the 8 artifacts. it is the same issue as on the abilities (bless/curse). if you move on the first (most left icon), then you see that item, and if you then move over to the next item, you stil lsee the tooltip for the first item. I have unlock 2 artifacts, and if i move over the first one i see flat turret info, and if i move to the second one, it stil says flat turrent damage. now, if i reload the game and first move onto the second item, then i see the correct info in the tooltip, but as soon as i move over the first one, then again the tooltip for the second one displays the first tooltip.
the curse icon is stil lshowing the bless info, if you first move over the bless icon. and now that the other icons no longer have tooltips if not unlocked, cant see the curse tooltip at all. and like bless, what is curse doing ?
ok, update on the no opponents showing up. getting through these waves without visible actions means NO XP, so no stat points. so I am now at wave 700, but only on level 55 and so my stats for this run are very very low
about the opponents not appearing. i just went from wave 649 to 674 without a single opponent being displayed and without a single shoot from my turrets displayed. and then just ONE opponent showed. happened earlier from like wave 1 to 100 maybe a total of 10 opponents were visible. happened after your latest patch. but the wave numbers go up, and it seems i get drops and levels and coins, just NOTHING is showing on the map as action for that whole time.
about 1 and 7, as mentioned did reload, and still they are looking very much alike, to be honest i dont recognize ANY change between the numbers from before and after your latest patch.
