Describe the bug
When place source (from receptacle) above rudimentary extractor or place rudimentary extractor under the source (placed from receptacle), the source may disappear with some chance (about 50%)

Minecraft 1.21.1, Neoforge Elementalcraft 7.0.2

Additional info:

1. Source disappears, but some fluid is collected in the Container below the extractor.
2. There are no info in Elementopedia about some probability of source disappearing.

Update:
Fire source "at home" may disappear even after successful move after some time and with source stabilizer (!!!)

After 30 min playing only 3 of 6 fire sources rest. Stabilizers dropped. Other elements do not lose sources (6 of 6).

Sources changed a lot in latest update and get estroyed instead of recovering over time like they used to, this should be described in elementopedia. To compensate those changes there should be al ot mor source spawning in the world and source breeding is now a reliable way to get new sources.

Do you experiance sources disapearing too fast ?

After eternal sources any disappearing is too fast :) Especially when they disappear instantly. May be some of them have volume smaller than container and extractor just eats whole source? Do not know...

Elementopedia says about old sources behavior: go to recovery state (not disappear) and resume.

About fire sources: they used more frequently to craft fireite and pure ore and may be therefore disappears. Also dry-hot biomes are rare, so they especially hard to find, so probably, I need breeding.

Elementopedia entry for breeding still isn't accessible. Probably, it should be in the "Sources" page and become accessible early, may be opened after craft receptacle to say player about alternative.

JEI shows that breeding is extremely expensive and requires big amount of source especially fire (again fire). I afraid production steps may consume more source than effect from new source.

You probably disagree, but I think old mechanics is better WITH breeding. My points:

1. It's not good then automated line suddenly breaks. If you have huge base, it may consume some time when understand, what's happened.
2. It's not aesthetic and atmospheric, when too many sources are around. I would prefer some long search for 1 but eternal source, and later use breading to steady multiplicate it from 1 to 4-6.
3. Search new sources again and again is much worse and way boooring :)
