Last few days I’ve been getting random world age errors. Here is the code that triggers it now (the last line).
```julia
using DataFrames
using CSV
using GLM
using RCall
using Plots
#using PyPlot
using Mamba
using StatsPlots
dat = CSV.read("./regression_models/Leinhardt.csv")
cols = Symbol.(names(dat))
(nobs, nvars) = size(dat)
l = @layout grid(4,4)
plots = Plots.Plot{Plots.GRBackend}[]
# Plot data for visual inspection
for i = 1:nvars
for j = 1:nvars
if i != j
p = @df dat scatter(cols(cols[i]), cols(cols[j]))
push!(plots, p)
else
p = @df dat scatter(cols(cols[i]), cols(cols[j]))
push!(plots, p)
end
end
end
Plots.plot(plots..., layout=l, legend=false, size=(1200, 800))
## data is very right skewed, so lets take the log of the continous variables.
@. dat[!, :logincome] = log(dat[:, :income])
@. dat[!, :loginfant] = log(dat[:, :infant]) ## TRIGGERED HERE
```
The error is
```julia
julia> @. dat[!, :loginfant] = log(dat[:, :infant])
105-element SentinelArrays.SentinelArrayInternal Error: {ERROR: Float64MethodError: no method matching size(::SentinelArrays.SentinelArray{Float64,1,Float64,Missing,Array{Float64,1}})
The applicable method may be too new: running in world age 27138, while current world is 27283.
```
Ran the same line again and got
```julia
julia> Dict{String,Any}) at /home/affan/.vscode-server/extensions/julialang.language-julia-0.16.8/scripts/packages/JSONRPC/src/typed.jl:63
[5] macro expansion at /home/affan/.vscode-server/extensions/julialang.language-julia-0.16.8/scripts/packages/VSCodeServer/src/VSCodeServer.jl:83 [inlined]
[6] (::VSCodeServer.var"#53#55"{Bool,String})() at ./task.jl:358
```
and it just stuck there until I hit enter a few times.
Using VS Code.

This could be a variant of [https://github.com/julia-vscode/julia-vscode/issues/1338](https://github.com/julia-vscode/julia-vscode/issues/1338). I’ve been hitting this one a lot since the latest update as well.

We hope to push an update out tomorrow that fixes that, just need a few more hours on the insider channel with any major regressions.
