I have Billboards ,Vault and CMI plugin installed on my server.

When I rent a billboard and try to snake and place a sign on billboard to change the content of it, nothing happened.But when I disabled CMI plugin, the billboard will work correctly.Seems there's a bug with it.

Hope it will be fixed ,thanks :)

Server version: paperspigot 1.16.5

Billboards version: v2.3.1

I am not familiar with CMI. But from the feature list at their plugin page, they seem to have a feature called 'self updating signs'. There may also be other sign related features. Maybe their implementation of these features conflict with Billboards. However, CMI is closed source, so I can't check if this is the case, or what exactly the conflict is here.

My current guess is that maybe the CMI plugin forcefully cancels the interaction or block placement of the sign. The Billboards plugin relies on the sign being placed, so that Minecraft opens the sign editor for the player. The Billboards plugin already tries to enforce that the sign for editing a billboard is getting placed (for example to override protection plugins such as WorldGuard). But plugins may still be able to forcefully prevent this sign from getting placed. Maybe this is what is happening here.

But without access to CMI's source code I can't look into the issue or propose any solutions for how to best resolve this incompatibility. Your best bet is to contact the autors of the CMI plugin to look into the issue. If the issue actually is about forcefully preventing the sign placement, maybe they can be less strict about that, or limit it to specific signs only.

Thanks,I'll have a try.
