Ruins of the Vale Dungeon (Victini) - Maybe dumb suggestions for Kyurem bug???

Hello dear CONTENT SCRIPTERS,

Here's a suggestion and a question about Kyurem bug in Victini Dungeon.

1. Understand that the bug is strongly linked to server lag and desyncs.

If the bug appears due to lags, is it possible to disable the moving fireballs and electric lightning? (not the barriers, of course)
It's not a real difficulty in the dungeon and seems to create more map slowdowns than anything else.

2. Understand that an “alternative bug” making the 2 Kyurem reappear has been put in place to avoid a larger bug preventing them from spawning and completely blocking the dungeon.
Is it possible that the new script makes the same Kyurem appear twice at the same time? Very often, when killing a Kyurem does not deactivate the corresponding barrier, the Kyurem reappears in the same place.
For example, is it possible that the script is spawning a Kyurem-Black A and a Kyurem-Black B, both of which are linked to the same barrier? Killing #A wouldn't be enough, as the variable would still be linked to #B. This is just an idea and may not make sense.

Maybe everything above is dumb and doesn't make sense with your code. In which case, tell me.

Thank you,

Have fun.
