Mo' Bends is client-side only, which means it's only required on your Minecraft and not the server. I've checked the LDoH Tweaks page on CurseForge and it does not mention the requirement of Mo' Bends mod, although I see the author of the mod in some comments mentioning that it's required on the server, which doesn't make sense because the mod is not meant for the server.
The mod developer should be the one that fixes the problem.
I doubt they will solve it, apparently the mod has been around for a while without receiving updates. Wouldn't it be easier for Aternos to include ¨Mo Bend's¨ in their list of Mods? What happens is that there are some YouTubers too famous called Willyrex and Vegetta777 who are doing a minecraft series with these Mods and many people are wanting to play a server with them, I included of course in this, but it is impossible to make the server work with this mod , since it crashes for not being the mo bend's
