disable neutral victim and extra fleeing from towers

This is the 4'th warcraft 3 forum i've opened topic first let me introduce myself

I have a warcraft map 11 years old (i'm developing it when warcraft 3 roc released) and i have a great knowledge about triggering BUT this time someone should give me a hand.

I have a serious problem and i need to prevent neutral victim and neutral extra slots fleeing from towers

i've tried too many things but still i haven't find a solution yet

OR

when i've try to use slot 1 for refree players (slot 1 and slot 7 are none) player 1 and player 7 creeps can see invisible units.

I need to solve one of this problems

1-) Disable creeps seeing invisible units when they're controlled by slots (1-12)
or
2-) Disable creeps fleeing from towers if their healths gets low when they're controlled by neutral victim or extra slots

or if you have a different idea here is the slots

Team 1

player 1 none (using for team 1 creeps, structures etc etc)
player 2 human
player 3 human
player 4 human
player 5 human
player 6 human

Team 2

player 7 none (using for team 2 creeps, structures etc etc)
player 8 human
player 9 human
player 10 human
player 11 human
player 12 human

When we have a observers, i'm replacing player 1 and player 7 units as neutral victim and neutral extra and this solves my "creeps can see invisible units" BUT this time creeps fleeing from towers when their hit points gets low

I hope one of the experienced player can solve my problem.

One solution is to just make all towers into units

yes i know this trick but that affects too many things plus towers are not visible in the fog

Because recently I also had that problem, where creeps from neutral victim ran away from attacking buildings as soon as the creeps life dropped below 50%, here is my reply.

My forum search ended up with this thread:

Especially see post #11 from Rising_Dusk.

I for my way just started turning buildings into units by setting the appropriate field to false, like Fledermaus suggested. This works like a charm regarding the creeps movement. Other side efffects - like no fog animation - are okay for me, as there seriously seems to be no other good solution. To work arround the fog animation things, do what Rising_Dusk suggests: just use a dummy building unit for the visual part & a 2nd invisible unit which is no building for the combat part. Of course if there is another solution known now im also very interested in!

i've tried all of the things you've said but there are too many side effects and still i'm too looking for solutions :)
