Error when trying to reload a BSON file

[tszanalytics]

Up until today (10/30/2020) I have run the following code numerous times with no error. Today I get the following error:

using BSON: @load, @save
using AxisArrays
using CSV, DataFrames, Plots, StatsPlots, Distributions
using Turing, LinearAlgebra

@load "heterog_model_hmc_chains_02prior.bson" cc

ERROR: TypeError: in Type, in A, expected A<:(AxisArray{Union{Missing, Real},3,D,Ax} where Ax where D), got Type{Missing}

I have tried updating the packages. The same error occurs for different BSON files, so it's not a corrupted file.

It takes several hours to estimate the model, so I really need to be able to load the MCMC chains rather than keep running the model again. Any help would be greatly appreciated.

Thanks,
