I am testing version of ProjectE from pull request with your mod.
And it crashed when I placed External Storage with Transmutation table.

It is okey, ofcourse, but I thinked that I can fix it without your help.
In stacktrace I found thar problem were in this class:
com.raoulvdberge.refinedstorage.integration.projecte.StorageItemTransmutationTable.getStacks
Where can I find it? Here on main branch of your repository no files with this name.

I had downloaded virsion from GitHub andd compiled it. As I expected no support of ProjectE here.

Project e integration is removed, so don't except support for it.

Can you just give me link for sources with ProjectE api? Everything after that is my problem

Go the project E github

No, I mean your mod with integration code.

Go look in the github history.
