It was meant to have been https://github.com/TrinityCore/TrinityCore/commit/d1d0c64ad11cb3faf986a5332fec6b704fb8026c and has worked for me for quiet a while but maybe somebody else made custom changes to instance script, comparing

ye seems this file is different for me so ye someone made custom changes

Well seems boss states are supported just immol'thar does not seem to be changing bossstate but ok seems Immol'thar is not scripted either other than been made attackable and forcefield...

Append this for Immol'thar and it should work ~~~sql DELETE FROM smart_scripts WHERE entryorguid = 11496 AND `source_type`=0 AND `id`>5; INSERT INTO `smart_scripts` (`entryorguid`, `source_type`, `id`, `link`, `event_type`, `event_phase_mask`, `event_chance`,...

Well some progress on this ``` sql UPDATE `creature_template` SET `ainame`='SmartAI', `scriptname`='' WHERE `entry` =22189; DELETE FROM `smart_scripts` WHERE `entryorguid` =22189 AND `source_type`=0; INSERT INTO `smart_scripts` (`entryorguid`, `source_type`, `id`, `link`,...

Well the issue is with the spell used to possess the marmot seems the possessed creature becomes invisible and gets killed by unseen mobs (ogres) only the player who summoned...

Or maybe dbc spell I see in spell dbc there is spell 38578 [DND]Rexxar's Rodent Trigger but seems this spell has no effects as seems missing data

but still seems biggest issue is the hiding with the marmots you can see that marmot does not have this aura but player does but when charming marmot you still...

Apply the following and this makes the quest completable however you have to click the coax marmot aura off so you can see mobs and dont get killed by invisible...

Some more about the coax marmot spell this aura is correctly only getting cast on player not marmot however seems screen effect from player been invisible is applied to marmot...
