TFS 1.X+ [tfs 1.3] bug onSpawn??

[roriscrave]

Hi! I'm using tfs 1.3 downgraded 8.6 with default source code.
I realized that some monsters take too long to be born, in some cases they are not even born.
So I decided to do the test in a cave:
I started to kill all monsters, starting in point 1 and finish in points 2.
And then I waited for the respaw to be born.

What happened was that the respawn monster "d" was born before the respawn monsters (a, b, c).
But monsters a, b, c were killed before monster "d", isn't that wrong?
The bug happens that some monsters are spawn at the right time, others take 5, 10, 15 minutes and other not spawn more. Since the respaw time is the same for everyone.
How can I fix this bug?

1. Respawns are blocked if a player is occupying the space.
2. Initial respawn timers are configured in the Map editor (in the monster zone). (And perhaps manipulated in config.lua).

If Monster A and B are in monster zone 1, and monster C is in monster zone 2, if all three monsters are killed simultaneously, then Monster A and C will respawn first, then the next interval monster B will spawn.

1 - I killed all by a GM
2 - All have same time in map editor (60)

What is Monster Zone? If is a spawn in map editor, all have the same monster zone, i put only one zone biggest in this area.
