Describe the bug
Due to a part of Ender Remaster reworking how one enters the end, it optionally disables the ability to use Ender Eyes to activate the portal to encourage exploration; however, as a result of messing around in a test world, I've discovered that the frames you add also share this hindrance and worse part being is it not able to accept the other eyes the mod adds

To Reproduce
install spectrum (preferably deeper down alpha 19) and Ender Remastered

Expected behavior
any attempt to put an eye of ender in will not work and it seems that frames placed by players won't work properly

Mod version
Deeper Down Alpha 19

Crash Report
Non-applicable

did you miss word the expected behaviour part?

I don't think so

Trying to use ender eyes on places frames won't work and trying to use others will not work either

expected behaviour is what you think should happen/what you expected to happen

you seem to have just repeated observed/wrong behaviour

in this case expected behaviour could be "using eyes of ender on cracked frames would work like it does without end remastered"

it wouldn't surprise me if it's an end remastered issue
with how it handles preventing default behaviour

Looks like End Remastered globally disables the use of Eye of Enders on any block. Their deprecated forge branch only prevents the use of Eye of Ender on vanilla End Portal Frames. So for their own consistencies sake and for compat with all other mods that interact with Eyes of Ender that would better be corrected on their end.
