setWaterLevel causes clientcrash after some time

[ArranTuna]

Describe the bug
Dunno why, but if I use some flood script, it'll crash all clients after some time. I don't know a reason.

See steps to reproduce for serverside script I used. It's from the wiki, lol

To Reproduce
-- Setting water properties.
local level = 0
local SizeVal = 2998
-- Defining variables.
local southWest_X = -SizeVal
local southWest_Y = -SizeVal
local southEast_X = SizeVal
local southEast_Y = -SizeVal
local northWest_X = -SizeVal
local northWest_Y = SizeVal
local northEast_X = SizeVal
local northEast_Y = SizeVal

water = createWater ( southWest_X, southWest_Y, level, southEast_X, southEast_Y, level, northWest_X, northWest_Y, level, northEast_X, northEast_Y, level )

function part2( )
setElementPosition(localPlayer, -780, 463, 0)
for i=1, 100 do
a = createPed(0, -780 + math.random(-10, 10), 463 + math.random(-10, 10), 0)
setTimer(setPedControlState, 1000, 1, a, "fire", true)
end
setTimer(drainSomeWater, 50, 35000)
end
setTimer(part2, 2000, 1)

function drainSomeWater()
level = level + 0.1
setWaterLevel ( water, level )
end

Expected behavior
no crash

Still happening in 1.6
RpAnimBlendClumpGetAssociation fails for some reason (most likely nullptr), causing this crash
