This mod contains fuel cell, the author called so this entity as fuel cell and he has just the same name as well as the rocket fuel block? i installed this mod before ur mod and game thinks that it rocket fuel block from ur mod
The stack size fgrom his mod is 50, and when I try to change something in my inventory ur fuel cells with 1 stack size dropping out
So i qant to say there conflict with entity names

I am glad that you consider this a "tiny" conflict. If I were to try and do something about this in my mod, I run the risk of interfering with the progress of games in progress or worse. As this can involve 100+ hours of game play, I am not prepared to run this risk.

I will add that in my test play through of the bob's mods integration, I did not find myself with surplus sodium hydroxide, so it may not make much sense running these two mods together in any event.
