Minecraft version: 1.12.2
Wizardry version: 4.1.2
Environment: Server

Issue details: So once I summoned a spirit horse which died of suffication, when I was going down an incline. From then on it would not let me summon the spirit horse again. I don't know if its a issue with the spawning. In the gyazo video I am right clicking on the ground (even if you can't see the wand moving) and it does nothing. I can use a different spell as seen and that spell works fine.

Other mods involved: [only list mods that are relevant to the problem]

I'm on a 1.7.10 server and can confirm the spirit wolf issue. You can manually fix this by going to your world > playerdata > ForgeCaps > ebwizardry:wizarddata and setting hasSpiritHorse or hasSpiritWolf respectively to 0.

I don't know how the logic currently works, but perhaps it could always despawn the previous spirit horse(or any owned by the caster) and spawn a new one?

This is also a problem with the spirit wolf as well.

I used to have this issue during development, but I thought I'd fixed it... my guess is that for some reason, suffocation doesn't trigger the bit of code that tells the player they no longer have a spirit horse (and can summon another one). Either that or the server got out of sync, possibly if you logged out.

@ProsperCraft Now that is a neat idea. I think I'd actually prefer that mechanic anyway, and it'll certainly fix the issue. I'll implement that change for the next update.

The new behaviour suggested above has been implemented in the 4.2.0 release.
