Custom Mob Problem

[thanna]

So after researching for about 2 days now and concluded that 3999 is the is the max mob id for my client 2015-11-04aRagexe, So I made some custom mobs on the vacant ID's the problem is when the id is below 3970 the mob is too big when spawned. 3971 and above is fine until 3998.here is an example of the mob. I also check it on act editor/sprite editor and the size is just normal.

ahh well i can tell you that many mob ids are wonky where youll spawn mobs with glowing effects and the sort, might just be because i was also on an older client and havnt tried it since i upgraded 

i just dont get your problem, dont you have like 1.5k free ids under 4000
