Version Information (please complete the following information):

• Mod Version: 3.1.0.1-all
• Forge Version 47.3.12

Additional context
I'll admit I'm playing a kitchen sink pack I threw together, but I don't think there's anything that would alter the behavior of the gantry in it. Modpack link is https://www.curseforge.com/minecraft/modpacks/yeet-the-fourth

I'm playing with the exact same setup (though still using Forge 47.3.0) and I/we can't reproduce this:

I'm in creative, but my friend plays survival.. as you can see, they can easily attach the stone hammer arm onto an armor stand without any issues. Do your logs mention anything out of the ordinary by any chance?

So basically... we placed an armor stand, got the (stone) hammer arm and just placed it without any problems.

Known problem with Better Combat

From FredHoof on Discord:

[...] a simpler fix is adjusting Better Combat's fallback_compatibility JSON file to imclude "construct_hammer" as part of the blacklist.

Better Combat would need to support negative numbers for speeds, or include that into the blacklist by default in order to fix this issue permanently.
