Teleports that don't work are not giving any feedback

[Momshroom]

Description of Issue

If a teleport fails, presumably for being "unsafe" players are not getting told... they simply fail to teleport. No mention of an unsafe location, nor of anything else. No offer of /tpbypass. Just the player doesn't move.
Examples:
/home (name of home) - some homes just nothing happens
/patrol - if the player being patrolled is under water, in lava, etc, patrol says it is patrolling them but the admin doesn't actually move

Other plugins tps are also failing at times, usually silently, and only when CMI is installed. These are intermittent failures... sometimes they work.. then they stop working for everyone and then they start again. I do not know what causes the failures and, since they are intermittent, I cannot be sure they are related to CMI. Noting that they generally don't say they are failing, either, though /desc and /asc do -- they say no free space found (even when there is one... and sometimes moving to a different part of the block fixes them)
Examples:
/t spawn (towny town spawn command)
/n spawn (towny nation spawn command)
/thru (worldedit command)
/asc (worldedit command)
/desc (worldedit command)

I don't yet know if it fixed the other issue

[Momshroom]

Updating: I'm no longer seeing /t spawn, /n spawn, /thru, /asc and /desc failing, BUT:
New players are sometimes spawning where they are supposed to, and sometimes spawning at the world spawn rather than the server one, and dead players are sometimes respawning at their bed spawn rather than the server one.

[Momshroom]

And bypass perms don't matter: teleports just fail silently when they fail (like unsafe homes). No option to /tpbypass... you just don't go, but you do have the particle effects.

[Zrips]

Will add few things for teleportation processing methods which should trigger some error reports if there are any. Other than this, by any chance it could be related to chat bubbles? While we had some changes with it in recent updates there still might be some, especially with 3rd party plugin now allowing player to teleport while chat bubble is active

[Parthodys]

We have teleport issues on newest Towny as well, but we do not even have CMI. We do use the CMILib however, so it seems to stem from that one.
Our teleports that don't have any economy fee seem to work okay, but teleports that have a fee will not teleport at all.
