Problem Mods not playing nice together

[Quanti_Nol]

I am running FTB Infinity Evolved server and I loaded the Practicalities mod onto my server. Well, last night i decided i wanted to setup a spawner using Draconic Evolution. Problem is I have yet to see any mod souls from Draconic Evolution at all. I am wondering if the soul aspects from Practicalities is replacing/interfering with the DE mob souls because i get a metric ton of the soul aspects.

As a "part 2" to this question i decided to remove Practicalities from my server to see if that would cause mob souls to drop but when i remove the mod my server wont boot. I search the net and everything i found said just delete the .jar from the mods folder on your server but do so stops my server from booting.

Any help or advice would be greatly appreciated!

Thanks

I can't answer the first problem but for the second problem, my guess is that the server tells you that there are some blocks missing and wants you to confirm loading with /fml confirm command
