I noticed a few misconceptions here. The bug is more simple than is being explained.
- You dont have to be around mobs, any sort of terrain or have any negative effects on you for this to happen. It's as simple as this:
You can reproduce the bug simply by walking around anywhere. There seems to be places all around you that if you stand on it, some or most of your spells will grey out. They supposedly fixed this in one of the latest patches where you could cast even though it's greyed out, but this is not fixed. Simply walk around anywhere and you will find a spot where part or most of your spells will grey out.
Let's use healing for example. This is horrible since when you're fighting mobs, you have to move a distance before your heals will be available again. I noticed that often, you don't even have to move for the spells to grey out. It happens when:
- Being attacked by mobs
- Being casted on by mobs
- Someone near you casting a spell that doesn't even target you
- Skills like meditation will grey out if someone else uses any kind of skill or spell around you as though you used the skill actively yourself.
- Standing still and any actions take place
- Moving around without any actions taking place
*This happens with not just healing but many spells*
*This doesn't just happen to cursor target spells but to most spells no matter what you have them set up as for targeting*
I noticed the spells that it doesn't seem to happen to are summon type spells.
Funny thing is... if you use heal while it's greyed out, it will not work with either the button or the macro key you have it set to, BUT it will work by clicking heal on your lifebar. If you unlock and relock the macro bar, 'sometimes' it will come back for a short period of time, sometimes it will not.
When you die, if you have rune books or spellbooks in your macro bar, they will grey out until you either relog or unlock your task bar, pick up and drop the books back into the bar then lock the bar back. (by the way... whoever thought about putting locks on the first box in the macro bar really didn't think this through. More often than not, I click the damned lock instead of the spell because the lock is IN THE WAY! Right clicking the bar and choosing lock or unlock is perfectly good enough)
I use EC. Since one of the last patches, my EC has become all but impossible to use. It makes gameplay horrible and I hunt seldom because of it because when you need to cast spells to keep you alive at crucial times, they are not available and you DIE! CC doesn't work well on my monitor and I don't feel like programing endless spells and features back into macros. UO... You broke my beautiful EC!!!!
A few the bugs they listed as fixing in the latest patch notes have not been fixed. EC it riddled with bugs since the big change. Lifebars do not update, Bank Box still pops up as a list the first time you open it, setting a fel side rune as the default rune will send you to trammel side when using the book as a recall target, after you set it (must close client - the next time you open it this bug takes place until you set the rune as default again), lagged out bags when you first open then, lagged out bags when you open more than 4, items sometimes dont show until you put more than one item in a backpack, vendor search locks up, doesn't work, or closes while in your house or at the bank until some time passes.. It thinks you're in a fight. This also happens when mobs target you while you're in your house.
Soooo many more bugs that I could spend an hour listing them and I'd still forget some.
Edit: I should note that when your macros grey out, I have found that simply clicking something else around you will make them come back but targeting the mob again in this case will often make them grey out again. I would also like to make this clear, that you don't have to be around mobs for this to happen. It also happens along the back wall and various locations in my own house with no mobs or creatures around. I can simply walk around my house for this to happen.
