Incompatibility with Bedrockify
I've made a post on bedrockify here, I'm not sure if you two are able to work together to fix this? but heres what the issue looks like

Hmm, this'll be interesting, because they're replacing the screen that I'm editing. Tomorrow I'll try to see if I can get the screenshot to load on their screen instead of the panama.

The owner of bedrockify is looking into this aswall, you two may be able to work together on this one @juancarloscp52

As soon as the small fix is done on his side and is released, I'll release a version with the mod compat mixin.

Since the bug is fixed on their side, the compat is added on mine. I still want to fix a bug or two before doing a full release (not related to Bedrockify), but here's a beta release with Bedrockify's compat:
