 The call will return `null` if the statistics options are incorrect, or player didn't get these in their history. 
 If the player encountered the statistic, or game created for him empty one, it will return a number. 
 Scarpet will not affect the entries of the statistics, even if it is just creating empty ones. With `null` response 
-it could either mean your input is wrong, or statistic has effectively a value of `0`.

-### `plop(pos, what)`
-
-Plops a structure or a feature at a given `pos`, so block, triple position coordinates or a list of coordinates. 
-To `what` gets plopped and exactly where it often depends on the feature or structure itself. For example, all 
-structures are chunk aligned, and often span multiple chunks. Repeated calls to plop a structure in the same chunk 
-would result either in the same structure generated on top of each other, or with different state, but same position. 
-Most structures generate at specific altitudes, which are hardcoded, or with certain blocks around them. API will 
-cancel all extra position / biome / random requirements for structure / feature placement, but some hardcoded 
-limitations may still cause some of structures/features not to place. Some features require special blocks to be
-present, like coral -> water or ice spikes -> snow block, and for some features, like fossils, placement is all sorts 
-of messed up. This can be partially avoided for structures by setting their structure information via `set_structure`, 
-which sets it without looking into world blocks, and then use `plop` to fill it with blocks. This may, or may not work.
-
-All generated structures will retain their properties, like mob spawning, however in many cases the world / dimension 
-itself has certain rules to spawn mobs, like plopping a nether fortress in the overworld will not spawn nether mobs, 
-because nether mobs can spawn only in the nether, but plopped in the nether - will behave like a valid nether fortress.
-
-`plop` will not use world random number generator to generate structures and features, but its own. This has a benefit 
-that they will generate properly randomly, not the same time every time.
