Unable to build snow golem and iron golem regardless of any limit set

[Ritcheur]

Expected behavior

If no limit is set on snow golem or iron golem, one can spawn as many as they want by building them.

Observed/Actual behavior

Regardless of any limit set, we are unable to spawn any snow golem or iron golem when the Limits addon is active.

Steps/models to reproduce

• Have the BentoBox plugin and Limits addon active.
• Set up the limits' config file however you like (it can be left empty).
• Try building a snow golem or an iron golem.
• The blocks do not disappear, and no mob spawns.

I'm filing a Spigot bug on this as it seems to be a server issue.

[tastybento]

Filed as https://hub.spigotmc.org/jira/browse/SPIGOT-7565

[tastybento]

md5 says that I need to use a different API, so that's in progress. That yielded another bug https://hub.spigotmc.org/jira/browse/SPIGOT-7567

[tastybento]

md5 fixed the snowman bug but you'll need to wait for it to get into a release before it works. In the meantime, snowmen will spawn but leave behind blocks, which may suffocate them. That said, this update will work for Iron Golems and Withers fine now. You can get the latest from ci.bentobox.world. I'll do a release this weekend once the Spigot bug fix has made it to Paper, etc.
