just went to sell excess fluid and saw that the fluid buy GUI is not working (shows nothing, btw I have the fluid raw resources mod installed as well as the auto barrel[ie no barrel required for barreling]) for the fluid tank (V0.18.25)

the chest gui still works tho

can't reproduce.
do you mean nothing happens when you click the entity or you get a buggy gui or you get a vanilla tank gui?
maybe it would be best if you send me a savegame..

sell and buy tabs are there but no fluid show up to select and I think it might be a mod combo that causes it
one sec while I load up factorio cause the main save I have been using has replay mode enable so saves take a bit to load
that and I am pretty sure it will happen in a blank world cause of the combination of mods used

....hold on I had the tank out for a while and all of a sudden the buy GUI is working on its own randomly and where a random delay is coming from I don't know

i don't know it might be a simple delay of some sort that is happening in the background but I don't know how or why

thing is my save is in replay enabled mode

well its 2 am for me and i saw my email notification on my phone again and hopefully this "delay/bug" won't happen again

oh and the price for all were 0.0 for me when the fluids showed up randomly

yeah i'm fixing all of it^^ good that you sent me your save game^^

its online :)
you can now disable the improved performance setting
