Updating to BloodArsenal-1.7.10-1.2-2 causes another crash.

removing Blood Arsenal fixes the issues.

Your first issue is irrelevant since you're insanely outdated. The second issue was just fixed: #30 and #32

Thanks. The outdated can't be helped since there hasn't been a Horizons II:Daybreaker release in awhile. Do you know when 1.2.3 will be available for download? It's not on the Curse site yet.

Edit:
Of course it shows up for download right as I type that. ;-) Thanks.

Blood Arsenal 1.1-14 users need to update to the latest one to fix the VersionChecker crash.
Note that if you're playing Horizons, it was recently updated so no need to worry.

Neither removing the mod or updating to 1.2.3 fixes the issue on my server. Both actions introduce a torrent of errors and mismatched IDs.

I don't understand why everything worked fine then one day it all breaks out of the blue :(

Eh? Crash reports please

For transparency removing BloodArsenal did fix my issue. I tried to update it to what was available at the time (1.2.2) but in the end it was easier to remove it and wait for the pack to update. Instructing multiple users to delete and download an updated version is cumbersome at best.

I'll be happy to have BloodArsenal in the pack when it updates if everything works as intended.

Crashing all of my users(and myself) as well, removing from my server too.

Have this as well, custom modpack with BloodMagic-1.7.10-1.3.3-13 and BloodArsenal-1.7.10-1.1-14

Everything was working fine and then suddenly no one can log into the server - the client crashes ~(not tried creating local world)

Looks like something in the version check creating the client crash? Can't disable version check in the client config?
