Your spell has been interrupted

[kartikeya200]

Well, after some exhaustive googling and forum searching I haven't quite found any information on this issue, so here goes. I'm a complete newbie when it comes to anything to do with programming; I've set up a private server on my own computer via the new Windows installer and have basically been enjoying myself with a team of bots. A few weird issues here and there have mostly been resolved (or ignored), but this one is just boggling my mind.

Seemingly at complete random, I will get an issue where I can't cast a certain beneficial spell on myself without being interrupted. If it's not self only I can cast it on any of the bot team without issue even while being completely unable to cast it on myself. It's only ever beneficial spells and which spell also seems random, but when it happens I'll be unable to cast that spell on myself until some arbitrary point in the future, and nothing seems to help it when it happens, not zoning or logging or even resetting the server. It can be multiple beneficial spells or just one or two.

Other than the spells always being buffs of some sort, and always being able to cast them regardless on bots, nothing seems remotely consistent with this issue. The zone doesn't matter. The spot in the zone doesn't matter (I've had constant interrupts and the same spell working perfectly in the exact same spot). How long I've been playing doesn't matter. If I have bots out or what kind of bots doesn't seem to matter. Buff bar completely empty or partly full seems to make no difference.

To be clear, I'm not moving. Most of the time I'll have been standing still for at least a minute or two. To test, I've stood perfectly in one spot for several minutes, been interrupted when trying to cast on myself, then cast on a bot without moving at all and had no issue (and then when trying to cast on myself, interrupted again.)

So, I'm at a loss, and since I'm a newb, I'm not sure even where to start looking for the issue. This has happened on two clients (ROF and UF), and on two different installs of the ROF client from two different sources. I believe my server is fully up to date (used the automatic patcher and then manually recompiled). It could of course be lag, but my machine is pretty burly and really shouldn't be having any real issues communicating between server and client (both are running off of my D drive). Aside from bots rubberbanding (which seems to be a common bot thing) I've not had any real lag related issues.

The only other thing I can think of is that I've race-changed this character to a race that can't normally be that class, done via GM #permarace (dark elf ranger). I don't see how that could be causing the issue, but I'm mentioning it in the interest of thoroughness. The only edits to the database have been altering the quests that handle Vox and Naggy's banishment of higher level players, experience loss on death, corpse recovery, and a few raid boss respawn times.
