Script Error with NeoABS

[Scudmaster]

Hello,
I'm having a bit of a problem with NeoABS and I know that no one supports it anymore, but I would appreciate someone putting thier two-sense into this...
PROBLEM: I'm using hategroups to have two different monsters attack each other and every so often I'll get this error when they are fighting each other...

Script'  oEnemy Process' line 526: NoMethodError occurred.
undefined method `enemy_id' for nil:NilClass

Here's the line of script...

    enemy_id = (e_id > 0 ? $NeoABS.enemies[e_id].enemy_id : 0)

I hope that this is enough information to help someone come to a conclusion of this problem.
Like i said though this error doesn't occur all the time but it still occurs and I don't want to release a buggy game.

P.S. - The only other script I'm using is a custom menu script and a splashscreen script.

That is basically saying that $NeoABS.enemies[e_id] is returning nil. Try replacing that line with this:

enemy_id = ($NeoABS.enemies[e_id].nil? ? 0 : $NeoABS.enemies[e_id].enemy_id)
