I just added WRCBE to the pack and it works just fine. Just make sure you don't break the block under a receiver or transmitter, that will crash the game.
New subject:
I was thinking about maybe using your pack as my next single player pack. It's a toss between yours and another pack to be completely honest.
If it's ok with you I was planning on stream the pack and adding in Mystcraft and since it works and I might find a use for it WRCBE.
If you're not ok with it being streamed and or me adding those mods, I completely understand.
Side note:
I don't normally like to add in game changing mods to packs because I feel it takes away from what the pack maker had intended, however I think in the case of these 2 mods should be ok since you've said you would add Mystcraft if your system could handle it and I would like to think that you would have added WRCBE but for the fact you say you it had crashed the pack for you (not completely sure what that means unless it's like what I mentioned above).
Oh one last thing
I tried to add Opis because I've gotten use to MapWriter minimap and I like some of the other features that Opis adds along with MapWriter. It crashes with your pack. I tried from v1.1.2 as well as both of the 1.1.3a and 1.1.3a_alpha versions with the same result. The problem is within Opis itself and the pack, since MapWriter alone works just fine in the pack.
WRCBE Crashed the pack in a previous version (1.4.0.6 I believe) however 1.4.0.7 is out so I will be adding it to the pack. Though if breaking the block under a receiver or transmitter crashes servers, and not just clients, it will be included, but disabled.
On the "New Subject":
I have two thoughts here:
1. Go ahead and stream it, however if you add mods, make it explicitly stated somewhere that the added mod is not actually in the download.
2. If you can get Mystcraft to work and would like to do the following, tell me: I can add Myst to the pack as a disabled mod (assuming I get permission), using your config, and take notes about other configs that may need to be changed. If you want to do this, you would essentially be supporting the mod for me. (Message me if this sounds like something you want to do)
Last thing:
Opis I may look into, however I will not be supporting multiple maps, you are fine to use them, but any issues they cause, or if for any reason they dont work, that is something that I will not fix.
edit: From the opis post on MCForum:
If you are using MapWriter already, REMOVE IT. I'm providing my own modified version along with Opis. If you have both installed at the same time, you will get an error when you start the game. Don't complain, you have been warned.
So I assume that it is actually part of the mod?
Would be happy to join but it seems like the server is offline
Sorry about that, I forgot that I had updates enabled on the server, so it restarted its self, it is up now, and the updates have been switched to manual.
