dragonflagon-fvtt VS fvtt-loot-sheet-npc-5e

In the meantime I'd suggest using DF Architect and DF Curvy Walls to make your life easier. There aren't many maps I've seen which can't have their walls draw manually in a few minutes.

DragonFlagon Curvy Walls - tools for drawing curved walls

Dungeondraft is going to be better for creating full maps. Foundry isn't awful for creating maps, particularly with the right modules - the DragonFlagon ones like Architect and Curvy Walls are great, so is Dungeon Draw for on-the-fly stuff - but at the end of the day, map-making softwares are better for making maps to then export to Foundry for use.

Also, DF Hotkeys should let you rebind many (most?) keys that are already registered in Foundry.

DF Manual Rolls: Allows toggleable behavior for requesting manual rolls, inserting that value into regular roll actions

This is a known issue. Unfortunately I haven't had the spare time to get through my back-log of issues yet. But you can keep an eye on this ticket: https://github.com/flamewave000/dragonflagon-fvtt/issues/297

DragonFlagon Active Lights

DF Chat Enhancements has capabilities for logging in addition to other things, and it does a really good job.

DragonFlagon Chat Enhancements https://github.com/flamewave000/dragonflagon-fvtt/tree/master/df-chat-enhance I'm mostly using this mod for the ability to edit chat messages. The idea is that players would use this to state their actions, and then be able to change their mind later if someone else does something unexpected, or does something that would cause the original actions to "fizzle".

LootsheetNPC5e: Everything Loot. Trading, merchants, lootable tokens, etc.

Loot Sheet NPC 5e was just updated to v9 today, you need to use the manifest link in the bottom of their Github README and not just update through Foundry, that seems to fail.

For the second issue - after a quick glimpse at the github for the module, a few people are submitting issues that splitting is not working. Seems like you are being hit by this bug especially hard as for most people it's jsut that - not working.

they are working on an update, should be ready in a few days, you can try the module item piles which has a slightly different approach and works in v9

This module is "the killer app" that really sold me on Foundry, but I've also had a lot of trouble with it working correctly for nearly a year, with different problems along the way. It would be more helpful if you could copy any error information from the console (press f12 on Chrome or Firefox). But a better place to read about or report errors would be the module's github page https://github.com/jopeek/fvtt-loot-sheet-npc-5e/issues

If that doesn't help, all you can really do is submit an issue on the github (https://github.com/jopeek/fvtt-loot-sheet-npc-5e) with as much information as possible (as it's possibly something unique to your setup) and hope that the dev updates it.

Keep a look at https://github.com/jopeek/fvtt-loot-sheet-npc-5e/issues/149 You can set up a notification once the changes are pushed! :D
