HTOA 3.x.x instance render bug ?!

In previous version 2.2.3 when i use INSTANCE and point attribute "instance" with for example "/obj/geo1" and render - all ok! Htoa use "/obj/geo1" as instance and correct render, low memory, etc. In version 3.0.0(3.0.1) when i try render same scene or use same method - htoa quickly takes all my RAM... Finish :(

In new version something changed with instance or this is bug?

Thank you...

I just rendered a simple test with 100k instances with the Instance object. Do you have repro scene (as scene that reproduces the problem)?

First screenshot is 2.2.3 version - all render OK(!), Second - 3.0.0 - all memory occupied in few seconds, computer freeze and full finish :(

I tested on two different computers with Linux and Windows ...

The question remains open ...
