Strange. Can you attach the map where it doesn't work? Also, here's a list of possible reasons why it couldn't cast in general:
• The caster doesn't have enough mana.
• The caster is not within range.
• The spell is on cooldown.
• Logic error with code.
Although your attached map works fine, so that is why I ask for the non-working map.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
